Abstract
This mathematical study focuses on the behaviour of coronary blood flow in coronary arteries during Angina. Blood is modelled as non-Newtonian fluid. Here blood is represented as Power Law fluid model and flow model is shown by the equation of motion and the equation of continuity. Using appropriate boundary conditions, numerical expression for volumetric flow rate, pressure drop and wall shear stress have been derived. Affect the coronary circulation directly as an externally viscous force compressing the blood vessels or they may act indirectly by producing changes in the blood-pressure drop, that is, by altering the pressure perusing the coronary arteries. Any of these factors may alter the coronary blood flow or change the distribution of the flow between the two phases of the heart beat. The role of hematocrit is explicit in the determination of blood pressure in the case of angina. The hematocrit increase the blood pressure drop is also increase. The overall presentation is in tensorial form and solution technique adapted is analytical as well as numerical.
