The fresh water reserves are being polluted due to expanding irrigation, industries, urban population and its development. Contaminated water leads to several health problems. With the increasing demand of fresh water, solar distillation is an alternate solution which uses solar energy to evaporate water and then to condense it, thereby collecting distilled water within or outside the same system to use it as potable water. The structure that houses the process is known as a 'solar still'. In this paper, ‘Modified double slope solar still (MDSSS)’ & 'Modified double slope basin type multiwick solar still (MDSBMSS)' have been designed to convert saline, brackish water into drinking water. In this work two different modified solar stills are fabricated to study the performance of these solar stills. For modification of solar stills, Fibre Reinforced Plastic (FRP) and Acrylic sheets are used. The experiments in MDSBMSS and MDSSS was carried on 10 September 2015 & 5 November 2015 respectively. Performances of the stills were investigated. The amount of distillate has been found 3624 Ml/day in MDSBMSS on 10 September 2015 and 2400 Ml/day in MDSSS on 5 November 2015. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contaminated%20water" title="contaminated water">contaminated water</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20solar%20still" title=" conventional solar still"> conventional solar still</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20solar%20still" title=" modified solar still"> modified solar still</a>, <a href="https://publications.waset.org/abstracts/search?q=wick" title=" wick"> wick</a> </p> <a href="https://publications.waset.org/abstracts/37145/experimental-study-on-modified-double-slope-solar-still-and-modified-basin-type-double-slope-multiwick-solar-still" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37145.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">432</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3896</span> Experimental Testing of Solar Still with Movable Inclined Surface and Equipped with Wick</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20N.%20Shmroukh">Ahmed N.

The proposed modified solar still was compared with the conventional simple still. The results showed that the daily produced desalinated water of the modified solar still with angles 105, 125 and 160 increased by approximately 13.7%, 27.9%, and 39.2%, respectively, compared with the conventional solar still. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20still" title="solar still">solar still</a>, <a href="https://publications.waset.org/abstracts/search?q=inclined%20still" title=" inclined still"> inclined still</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20materials" title=" porous materials"> porous materials</a>, <a href="https://publications.waset.org/abstracts/search?q=Wick" title=" Wick"> Wick</a> </p> <a href="https://publications.waset.org/abstracts/172980/experimental-testing-of-solar-still-with-movable-inclined-surface-and-equipped-with-wick" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3895</span> Performance Optimization of Low-Cost Solar Dryer Using Modified PI Controller </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kondareddy">Rajesh Kondareddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Prakash%20Kumar%20Nayak"> Prakash Kumar Nayak</a>, <a href="https://publications.waset.org/abstracts/search?q=Maunash%20Das"> Maunash Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Vrinatri%20Velentina%20Boro"> Vrinatri Velentina Boro </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, there is a huge global concern for sustainable development which would include minimizing the consumption of non-renewable energies without affecting the basic global economy. Solar drying is one of the important processes used for extending the shelf life of agricultural products. The performance of a low cost automated solar dryer fitted with cascade control scheme and modified PI controller for drying chilli was investigated. The dryer was composed of designed solar collector (air heater) fitted with cylindrical pipes to improve the air velocity and a solar drying chamber containing rack of two cheese cloth (net) trays both being integrated together. The air allowed in through air inlet is heated up in the solar collector and channelled through the drying chamber where it is utilized in drying (removing the moisture content from the food substance or agricultural produce loaded). Here, to maintain the temperature in the heating chambers and to improve performance, a modified PI (Proportional–Integral) controller was used due its simplicity and robustness. Drying time for drying chilli from the initial moisture content of 88.5% (wb) to 7.3% (wb) was estimated to be 14 hours in solar dryer whereas 32 h was observed in the open sun drying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cascade%20control" title="cascade control">cascade control</a>, <a href="https://publications.waset.org/abstracts/search?q=chilli" title=" chilli"> chilli</a>, <a href="https://publications.waset.org/abstracts/search?q=PI%20controller" title=" PI controller"> PI controller</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20dryer" title=" solar dryer"> solar dryer</a> </p> <a href="https://publications.waset.org/abstracts/45003/performance-optimization-of-low-cost-solar-dryer-using-modified-pi-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45003.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3894</span> A Platform to Analyze Controllers for Solar Hot Water Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aziz%20Ahmad">Aziz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillermo%20Ramirez-Prado"> Guillermo Ramirez-Prado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Governments around the world encourage the use of solar water heating in residential houses due to the low maintenance requirements and efficiency of the solar collector water heating systems.

The proposed model is adaptable to any households and location. The model can be used to test different types of controllers and can provide efficiency as well as economic analysis. The proposed model is based on the heat and mass transfer equations along with assumptions applied in the model which can be modified for a variety of different solar water heating systems and sizes.

Consequently, and since the conventional sources of water are limited, researchers devoted their efforts to oceans and seas for obtaining fresh drinkable water by thermal distillation. The current work is dedicated to the design and fabrication of modified solar still model, as well as conventional solar still for the sake of comparison. The modified still is single slope double basin solar still. The still consists of a lower basin with a dimension of 1000 mm x 1000 mm which contains the sea water, as well as the top basin that made with 4 mm acrylic, was temporarily kept on the supporting strips permanently fixed with the side walls. Equally ten spaced vertical glass strips of 50 mm height and 3 mm thickness were provided at the upper basin for the stagnancy of the water. Window glass of 3 mm was used as the transparent cover with 23° inclination at the top of the still. Furthermore, the performance evaluation and comparison of these two models in converting salty seawater into drinkable freshwater are introduced, analyzed and discussed. The experiments were performed during the period from June to July 2018 at seawater depths of 2, 3, 4 and 5 cm. Additionally, the solar still models were operated simultaneously in the same climatic conditions to analyze the influence of the modifications on the freshwater output. It can be concluded that the modified design of double basin single slope solar still shows the maximum freshwater output at all water depths tested. The results showed that the daily productivity for modified and conventional solar still was 2.9 and 1.8 dm³/m² day, indicating an increase of 60% in fresh water production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=freshwater%20output" title="freshwater output">freshwater output</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20still" title=" solar still"> solar still</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20desalination" title=" thermal desalination"> thermal desalination</a> </p> <a href="https://publications.waset.org/abstracts/104867/an-experimental-investigation-on-productivity-and-performance-of-an-improved-design-of-basin-type-solar-still" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104867.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3891</span> Investigating the Impact of Solar Radiation on Electricity Meters’ Accuracy Using A Modified Climatic Chamber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hala%20M.%20Abdel%20Mageed">Hala M.

In this work, the (MKF-240) climatic chamber has been modified to act as a solar simulator at the Egyptian national institute of standard, NIS. Quartz Tungsten Halogen (QTH) lamps and an Aluminum plate are added to the climatic chamber to realize the solar test conditions. Many experimental trials have been performed to reach the optimum number of lamps needed to fulfil the test requirements and to adjust the best uniform test area. The proposed solar simulator design is capable to produce irradiance up to 1066 W/m2. Its output radiation is controlled by changing the number of illuminated lamps as well as changing the distance between lamps and tested electricity meter. The uniformity of radiation within the simulator has been recognized to be 91.5 % at maximum irradiance. Three samples of electricity meters have been tested under different irradiances, temperatures, and electric loads. The electricity meters’ accuracies have been recorded and analyzedfor eachsample. Moreover, measurement uncertainty contribution has been considered in all tests to get precision value. There were noticeable changes in the accuracies of the electricity meters while exposed to solar radiation, although there were no noticeable distortions of their insulationsand outer surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation" title="solar radiation">solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20simulator" title=" solar simulator"> solar simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=climatic%20chamber" title=" climatic chamber"> climatic chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=halogen%20lamp" title=" halogen lamp"> halogen lamp</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20meter" title=" electricity meter"> electricity meter</a> </p> <a href="https://publications.waset.org/abstracts/152458/investigating-the-impact-of-solar-radiation-on-electricity-meters-accuracy-using-a-modified-climatic-chamber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3890</span> Energy Dynamics of Solar Thermionic Power Conversion with Emitter of Graphene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olukunle%20C.%20Olawole">Olukunle C.

Greenhousing is the first one of the agricultural activities that solar energy can be used directly in. Greenhouses offer us suitable conditions which can be controlled easily for the growth of the plant and they are made by using a covering material that allows the sun light entering into the system. Covering material can be glass, fiber glass, plastic or another transparent element. This study investigates the solar energy usability rates and solar energy benefiting rates of a semi-spherical (modified arch) type greenhouse system according to different orientations and positions which exists under climatic conditions of Bayburt. In the concept of this study it is tried to determine the best direction and best sizes of a semi-spherical greenhouse to get best solar benefit from the sun. To achieve this aim a modeling study is made by using MATLAB. However this modeling study is running for some determined shapes and greenhouses it can be used for different shaped greenhouses or buildings. The basic parameters are determined as greenhouse azimuth angle, the rate of size of long edge to short and seasonal solar energy gaining of greenhouse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=greenhousing" title="greenhousing">greenhousing</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20radiation" title=" direct radiation"> direct radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/31143/solar-calculations-of-modified-arch-semi-spherical-type-greenhouse-system-for-bayburt-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31143.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">479</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3888</span> Efficiency Enhancement in Solar Panel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20Arun%20Raj">R.

This paper reports the synthesis and characterization of partially oxidized graphite oxide (GTO). GTO was obtained by modified Hummers method, which is based on the chemical oxidation of natural graphite. Several samples were prepared with different oxidation degree by an adjustment of the oxidizing agent’s amount. The effect of the oxidation degree on the chemical structure and on the morphology of GTO was determined by using Fourier transform infrared (FT-IR) spectroscopy, Energy Dispersive X-ray Spectroscopy (EDS), and scanning electronic microscope (SEM). The thermal stability of GTO was evaluated by using thermogravimetric analyzer (TGA) in Nitrogen atmosphere. The results indicate high degree oxidation of graphite oxide for each sample, proving that the process is efficient. The GTO synthesized by modified Hummers method shows promising characteristics. Graphene oxide (GO) obtained by exfoliation of GTO are recognized as a good candidate for thermal energy storage, and it will be used as solid shell material in the encapsulation of phase change materials (PCM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modified%20hummers%20method" title="modified hummers method">modified hummers method</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite%20oxide" title=" graphite oxide"> graphite oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation%20degree" title=" oxidation degree"> oxidation degree</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy%20storage" title=" solar energy storage"> solar energy storage</a> </p> <a href="https://publications.waset.org/abstracts/117537/synthesis-and-characterization-of-partially-oxidized-graphite-oxide-for-solar-energy-storage-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117537.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3886</span> A Technical-Economical Study of a New Solar Tray Distillator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderrahmane%20Diaf">Abderrahmane Diaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Assia%20Cherfa"> Assia Cherfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Karadaniz"> Lamia Karadaniz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple tray solar distillation offers an interesting alternative for small-scale desalination and production high quality distilled water at a competitive cost using solar energy.

Thus, solar water heater is a device used to harness solar energy. In this paper, a modified solar water heating system (MSWHS) has been proposed over flat plate collector (FPC) and Evacuated tube collector (ETC). The modifications include selection of materials other than glass, and glass wool which are conventionally used for fabricating FPC and ETC. Some modifications in design have also been proposed. Its collector is made of double layer of semi-cylindrical acrylic tubes and fibre reinforced plastic (FRP) insulation base. Water tank is made of double layer of acrylic sheet except base and north wall. FRP is used in base and north wall of the water tank. A concept of equivalent thickness has been utilised for calculating the dimensions of collector plate, acrylic tube and tank. A thermal model for the proposed design of MSWHS is developed and simulation is carried out on MATLAB for the capacity of 200L MSWHS having collector area of 1.6 m2, length of acrylic tubes of 2m at an inclination angle 25° which is taken nearly equal to the latitude of the given location.

In the present work, measured data of bright sunshine hour of the region have been used to estimate the global and diffuse solar radiation. The regression coefficient 'a' and 'b' have been calculated using first order Angstrom type co-relation. The result obtained shows that the contribution of direct solar radiation is low and diffuse radiation is high during the monsoon months July and August for Karachi and Hyderabad. The sky remains clear from September to June, whereas for Nawabshah the global radiation remains high throughout the year. The potential of grid quality solar photovoltaic power in Karachi is estimated for 10 square meter area of solar panel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20potential%20over%20Sindh" title="solar potential over Sindh">solar potential over Sindh</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20and%20diffuse%20solar%20radiation" title=" global and diffuse solar radiation"> global and diffuse solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20over%20three%20cities%20of%20Sindh" title=" radiation over three cities of Sindh"> radiation over three cities of Sindh</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20panels" title=" solar panels"> solar panels</a> </p> <a href="https://publications.waset.org/abstracts/3864/solar-radiation-studies-and-performance-of-solar-panels-for-three-cities-of-sindh-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3864.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3877</span> CFD Analysis of Passive Cooling Building by Using Solar Chimney for Mild or Warm Climates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naci%20Kalkan">Naci Kalkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ihsan%20Dagtekin"> Ihsan Dagtekin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents the design and analysis of solar air-conditioning systems particularly solar chimney which is a passive strategy for natural ventilation, and demonstrates the structures of these systems’ using Computational Fluid Dynamic (CFD) and finally compares the results with several examples, which have been studied experimentally and carried out previously.

A detailed analysis of global solar radiation values measured using several methods is presented. These values are then compared with the NASA SSE model. The variation in direct and diffuse components of solar radiation is observed in summer and winter months for Islamabad along with the clearness index KT. The diffuse solar radiation is found maximum in the month of July. Direct and beam radiation is found to be high in the month of April to June. From the results it appears that with the exception of monsoon months, July and August, solar radiation for electricity generation can be utilized very efficiently throughout the year. Finally, the mean bias error (MBE), root mean square error (RMSE) and mean percent error (MPE) for global solar radiation are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20potential" title="solar potential">solar potential</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20and%20diffuse%20solar%20radiation" title=" global and diffuse solar radiation"> global and diffuse solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamabad" title=" Islamabad"> Islamabad</a>, <a href="https://publications.waset.org/abstracts/search?q=errors" title=" errors"> errors</a> </p> <a href="https://publications.waset.org/abstracts/3867/solar-radiation-studies-for-islamabad-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3867.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">437</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3875</span> Solar Energy for Decontamination of Ricinus communis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmo%20Thiago%20Lins%20C%C3%B6uras%20Ford">Elmo Thiago Lins Cöuras Ford</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Alessandra%20Carvalho%20do%20Vale"> Valentina Alessandra Carvalho do Vale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The solar energy was used as a source of heating in Ricinus communis pie with the objective of eliminating or minimizing the percentage of the poison in it, so that it can be used as animal feed.

The efficiencies were compared with the solar panels without any efficiency improvement technique. The efficiency of each setup was computed on an hourly basis every day for a month. The study compared the efficiencies and combined systems that significantly improved at a specific time of the day. The data showed that the solar tracking system had the highest efficiency during 6:00 AM to 7:45 AM. Then after 7:45 AM, the combination of both solar tracking and water-spray cooling system was the most efficient to use up to 12:00 NN. Meanwhile, from 12:00 NN to 12:45 PM, the water-spray cooling system had the significant contribution on efficiency. From 12:45 PM up to 4:30 PM, the combination of both systems was the most efficient, and lastly, from 4:30 PM to 6:00 PM, the solar tracking system was the best to use. The study intended to use solar tracking or water-spray cooling system or combined systems alternately to improve the solar panel efficiency on a specific time of the day. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20panel%20efficiency" title="solar panel efficiency">solar panel efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20panel%20efficiency%20technique" title=" solar panel efficiency technique"> solar panel efficiency technique</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20tracking%20system" title=" solar tracking system"> solar tracking system</a>, <a href="https://publications.waset.org/abstracts/search?q=water-spray%20cooling%20system" title=" water-spray cooling system"> water-spray cooling system</a> </p> <a href="https://publications.waset.org/abstracts/122446/characterization-of-solar-panel-efficiency-using-sun-tracking-device-and-cooling-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3872</span> Experimental Study of Solar Drying of Verbena in Three Types of Solar Dryers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Llham%20Lhoume">Llham Lhoume</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Tadili"> Rachid Tadili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nora%20Arbaoui"> Nora Arbaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most crucial ways to combat food insecurity is to minimize crop losses, food drying is one of the most organic, effective, low-cost and energy-efficient food preservation methods.
