Abstract
A mathematical model of blood flow in single arteries and arterioles subject to both the pulsatile pressure gradient due to normal heart action and a single cycle of body acceleration is presented. The body acceleration is such that it increases from zero to a maximum value at a uniform rate, remains constant at this maximum value for some time and thereafter returns to zero at a uniform rate. To account for the red cells in blood, blood is considered to be a two-phase fluid, that is, a suspension of red cells in plasma. Numerical results are presented for the effects of body acceleration on flow variables, such as, flow rate, velocity, acceleration and shear stress corresponding to the flow of blood in the human aorta and arterioles.
