NUMERICAL STUDY ON THE BLOOD FLOW CHARACTERISTICS OF STENOSED AND BIFURCATED BLOOD VESSELS WITH A PHASE ANGLE CHANGE OF A PERIODIC ACCELERATION

2008

The present study is carried out in order to investigate the effect of the periodic acceleration in the stenosed and bifurcated blood vessels. The blood flow and wall shear stress are changed under body movement or acceleration variation. Numerical studies are performed for various periodic acceleration phase angles, bifurcation angles and section area ratios of inlet and outlet. It is found that blood flow and wall shear stress are changed about and as acceleration phase angle variation with the same periodic frequency. also wall shear stress and blood flow rate are decreased as bifurcation angle increased.
