Manimaran PY - 2011/2/ TI - CFD Simulation of Non-Newtonian Fluid Flow in Arterial Stenoses with Surface Irregularities T2 - International Journal of Mechanical and Mechatronics Engineering SP - 185 EP - 191 VL - 5 SN - 1307-6892 UR - https://publications.waset.org/pdf/4504 PU - World Academy of Science, Engineering and Technology NX - Open Science Index 49, 2011 N2 - CFD simulations are carried out in arterial stenoses with 48 % areal occlusion. Non-newtonian fluid model is selected for the blood flow as the same problem has been solved before with Newtonian fluid model. Studies on flow resistance with the presence of surface irregularities are carried out. Investigations are also performed on the pressure drop at various Reynolds numbers. The present study revealed that the pressure drop across a stenosed artery is practically unaffected by surface irregularities at low Reynolds numbers, while flow features are observed and discussed at higher Reynolds numbers.
