PULSATILE FLOW OF 3RD GRADE FLUIDS UNDER BODY ACCELERATION - MODELINGBLOOD-FLOW

In normal life the human body is quite often subjected to acceleration . Prolonged exposure to such accelerations can generate significant ef fects on the blood circulation and its rheological behavior depending on the configuration and geometry of the blood vessels. The present st udy is concerned with a mathematical model for pulsatile blood flow su bjected to externally-imposed periodic body acceleration by considerin g blood as a third grade fluid. The effects of the body acceleration o n the velocity, the flow rate and the wall shear stress are estimated numerically through an implicit finite difference scheme for femoral a nd coronary arteries.
