performance and emissions in the lean operation (Ф=0.6-0.7) of a six-cylinder spark ignition engine fuelled with natural gas, pure methane and a mixture of hydrogen in methane (85 CH 4 , 15%H 2 by volume). Each fuel has been investigated at 1500 rpm and for various load conditions. Emissions, exhaust gas temperature and pressure cylinder were measured. The objective of the study is to determine how the load and equivalence ratio affect engine characteristics operating with natural gas and the hydrogen-methane mixture. The results show that the hydrogen addition increased HC and NO emissions, as well as the performance and cylinder pressure, but reduced the NOx, exhaust gas temperature and the CO and CO 2 emissions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0eea68fd0cfe651a937a883104385784" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":108368582,"asset_id":110601455,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/108368582/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="110601455"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="110601455"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 110601455;

Each fuel has been investigated at 1500 rpm and for various engine loads fixed by electrical power output conditions. CO, CO 2 , HC, and NOx emissions values, and exhaust gas temperature were measured. The effect of fuel composition on engine characteristics has been studied. The results show, that the hydrogen addition increased HC emissions (around 18%), as well as performance, whilst it reduced NO x (around 31%), exhaust gas temperature, CO and CO 2 .</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2786286db5009a218aea9212c4348c2e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":108368583,"asset_id":110601453,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/108368583/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="110601453"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="110601453"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 110601453;

The engine tests were conducted on 20, 30, and 40 N m constant loads and at full load condition. The experimental results show that the maximum cylinder gas pressures (Pmax) increased with an increasing engine speed and load. The location of the maximum cylinder gas pressure closed to top dead center (TDC) at high engine load. The starts of combustion (SOC) points closed to TDC at high engine speeds. The ignition delay (ID) slightly decreased with the increase of the engine loads, and it increased with an increasing engine speed. However, as the total combustion duration (TC) increased with an increasing engine load, it decreased with high engine speeds. The exhaust emissions, such as nitrogen oxides (NOx), smoke opacity, unburned hydrocarbon (HC), and carbon monoxide (CO), were also discussed for different operating c...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="110601443"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="110601443"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 110601443;

This hydrogen injection has an impact on emissions and the performance of user equipment. The present work reports on an experimental study of the combustion of methane-hydrogen mixture with fuel rich transverse staggered injection. The 15 kW domestic boiler used was equipped with 16 burners (2 × 8). The aim of this work is to better understand the simultaneous effects of fuel rich staged combustion (O = 2.0 ÷ 4.0), hydrogen blending of methane (0 ÷ 45%) on pollutant emissions and efficiency while maintaining a compromise between high power, fuel economy and low emissions. The results show that NOx, CO2 emissions decrease, CO and CxHy emission values increase and thermal efficiency values decrease with increasing hydrogen percentage and fuel rich staggering combustion.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="102473517"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="102473517"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 102473517;

The thermometry with the thermocouple numerically compensated was used for determining the thermal fields of a premixed butaneair V shape flame. The structure of both the inert and reactive jet was studied for a Reynolds number of 7000. Turbulence is generated by a perforated grid situated upstream. The main results of the thermal field in the V shape flame have showed more important results and a representative form of the inner structure of the flame was then obtained. The study is to determine how the turbulence and equivalence ratio can affect the temperature field, the flame height, the variable progress and therefore the combustion process.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3387d0e029f69b37242469b2a214d2fa" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":100413699,"asset_id":99281193,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/100413699/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="99281193"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="99281193"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 99281193;

Based on the commercial CFD code Ansys fluent 17.0, different turbulence models including the standard k-ε model, the RNG k-ε model, the realizable k-ε model and the standard k-ω model were used to simulate the flow field in a simple burner. The eddy dissipation model with the global reaction schema was applied to model the turbulence reaction interaction in the flame region. A finite volume approach was used to solve the Navier-Stokes equations with the combustion model. Particularly, the effect of these turbulence models on the combustion characteristics was analyzed. The numerical predictions were validated by comparison with anterior experimental results. Moreover, the predicted axial and radial gradients of velocity in the standard k-ε are overall agreement with literature results.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="c0d7b1d8642b42ea0cc02e96a92fcddc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":97503028,"asset_id":95277215,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/97503028/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="95277215"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="95277215"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 95277215;

Passengers would prefer to use vehicles than trams, therefore road traffic will increase and this, will complicate more the state of traffic in cities. This study uses the opinion of tram users. The main objective is to show the strong characteristics that attract the population to use tram and also its weaknesses. This last, may be improved to reach the maximum satisfaction of users.

The Particle Image Velocimetry (PIV) is used to determine the dynamic fields, and Laser Sheet Tomography (LST) for the flame fronts. The turbulent main jet has a Reynolds number Re = 10 000. Turbulence is generated using perforated grids having three whose provide different inlet turbulence intensities. Velocity fields are measured for various equivalence ratio (F = 0.6-1.3) and different axial flame positions. For the reactive jet, interesting results are obtained concerning the dynamic field and the flame front. It is shown that radial profiles of U and V correspond to the axial positions located before the end of the potential core in the reactive jet. The velocity increases at the jet center to 20 m/s, and is less influenced by turbulent mixing in the flame. The greatest velocity and turbulent kinetic energy are obtained using the grid with the smallest ratio (d/M). Most important values of the radial velocity correspond to the lean flames.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="7f05859663fd1912fed89cf69c9b863c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":93894111,"asset_id":90290969,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/93894111/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="90290969"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="90290969"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 90290969;

Although the technical and technological progress realized by the humans in all domains. The road traffic remains a victim of increasing congestion when demand exceeds the capacity of the road infrastructure. In this case, the vehicle will slow down to the entrance of the road infrastructure, thereby forming a bottling in traffic. In the present work, the first step is to considering the different variables that characterize the progressive movement of vehicles on a road. In the aim to give a mathematical formulation which links the number of vehicles present at time “T” over a length “L” of the road. This enabled us to develop a mathematical model to regulate the traffic speed in real time. To validate the model, a real application is presented, who treat the congestion problem in Constantine city.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="90290967"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="90290967"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 90290967;

Each fuel has been investigated at 1500 rpm and for various load conditions. Emissions, exhaust gas temperature and pressure cylinder were measured. The objective of the study is to determine how the load and equivalence ratio affect engine characteristics operating with natural gas and the hydrogen-methane mixture. The results show that the hydrogen addition increased HC and NO emissions, as well as the performance and cylinder pressure, but reduced the NOx, exhaust gas temperature and the CO and CO 2 emissions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0eea68fd0cfe651a937a883104385784" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":108368582,"asset_id":110601455,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/108368582/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="110601455"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="110601455"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 110601455;

The engine tests were conducted on 20, 30, and 40 N m constant loads and at full load condition. The experimental results show that the maximum cylinder gas pressures (Pmax) increased with an increasing engine speed and load. The location of the maximum cylinder gas pressure closed to top dead center (TDC) at high engine load. The starts of combustion (SOC) points closed to TDC at high engine speeds. The ignition delay (ID) slightly decreased with the increase of the engine loads, and it increased with an increasing engine speed. However, as the total combustion duration (TC) increased with an increasing engine load, it decreased with high engine speeds.

This hydrogen injection has an impact on emissions and the performance of user equipment. The present work reports on an experimental study of the combustion of methane-hydrogen mixture with fuel rich transverse staggered injection. The 15 kW domestic boiler used was equipped with 16 burners (2 × 8). The aim of this work is to better understand the simultaneous effects of fuel rich staged combustion (O = 2.0 ÷ 4.0), hydrogen blending of methane (0 ÷ 45%) on pollutant emissions and efficiency while maintaining a compromise between high power, fuel economy and low emissions. The results show that NOx, CO2 emissions decrease, CO and CxHy emission values increase and thermal efficiency values decrease with increasing hydrogen percentage and fuel rich staggering combustion.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="102473517"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="102473517"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 102473517;

The thermometry with the thermocouple numerically compensated was used for determining the thermal fields of a premixed butaneair V shape flame. The structure of both the inert and reactive jet was studied for a Reynolds number of 7000. Turbulence is generated by a perforated grid situated upstream. The main results of the thermal field in the V shape flame have showed more important results and a representative form of the inner structure of the flame was then obtained. The study is to determine how the turbulence and equivalence ratio can affect the temperature field, the flame height, the variable progress and therefore the combustion process.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3387d0e029f69b37242469b2a214d2fa" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":100413699,"asset_id":99281193,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/100413699/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="99281193"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="99281193"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 99281193;

Based on the commercial CFD code Ansys fluent 17.0, different turbulence models including the standard k-ε model, the RNG k-ε model, the realizable k-ε model and the standard k-ω model were used to simulate the flow field in a simple burner. The eddy dissipation model with the global reaction schema was applied to model the turbulence reaction interaction in the flame region. A finite volume approach was used to solve the Navier-Stokes equations with the combustion model. Particularly, the effect of these turbulence models on the combustion characteristics was analyzed. The numerical predictions were validated by comparison with anterior experimental results. Moreover, the predicted axial and radial gradients of velocity in the standard k-ε are overall agreement with literature results.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="c0d7b1d8642b42ea0cc02e96a92fcddc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":97503028,"asset_id":95277215,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/97503028/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="95277215"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="95277215"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 95277215;

Without an optimal operation and a better service, the tram can’t be an efficient means of transport that may help in decongesting road traffic. Passengers would prefer to use vehicles than trams, therefore road traffic will increase and this, will complicate more the state of traffic in cities. This study uses the opinion of tram users. The main objective is to show the strong characteristics that attract the population to use tram and also its weaknesses. This last, may be improved to reach the maximum satisfaction of users. In addition, this article attempts to show the preferred means of transport for passengers who travel on the same line as the tram.

The Particle Image Velocimetry (PIV) is used to determine the dynamic fields, and Laser Sheet Tomography (LST) for the flame fronts. The turbulent main jet has a Reynolds number Re = 10 000. Turbulence is generated using perforated grids having three whose provide different inlet turbulence intensities. Velocity fields are measured for various equivalence ratio (F = 0.6-1.3) and different axial flame positions. For the reactive jet, interesting results are obtained concerning the dynamic field and the flame front. It is shown that radial profiles of U and V correspond to the axial positions located before the end of the potential core in the reactive jet. The velocity increases at the jet center to 20 m/s, and is less influenced by turbulent mixing in the flame. The greatest velocity and turbulent kinetic energy are obtained using the grid with the smallest ratio (d/M). Most important values of the radial velocity correspond to the lean flames.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="7f05859663fd1912fed89cf69c9b863c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":93894111,"asset_id":90290969,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/93894111/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="90290969"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="90290969"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 90290969;

In this case, the vehicle will slow down to the entrance of the road infrastructure, thereby forming a bottling in traffic. In the present work, the first step is to considering the different variables that characterize the progressive movement of vehicles on a road. In the aim to give a mathematical formulation which links the number of vehicles present at time “T” over a length “L” of the road.
