The study assumed that the blood is Newtonian in character, incompressible and the flow is unidirectional, and in this case axisymmetric rectilinear. In this study we start by general introduction where biological and mathematical tool needed for physiological flow are well highlighted. This is covered in chapter one. In chapter two, literature review is in place followed by modeling and analysis of pulsatile flow of blood under body exercise. Presentation and discussion of results is done in chapter five. Blood was considered as non Newtonian in character. Method of lines was used to tackle the problem. The simulations were done using matlab and maple. Graphical solutions of both time dependent momentum equation and the energy equation are in place.The study found that the increase of body acceleration increases the velocity of blood and temperature. It is also found that as stenotic height increases the velocity decreases. It is further shown that increasing the hematocrit ratio increases the velocity of the fluid. On the other hand increasing the radial distance, decreases the temperature profile. Also, as radial distance () increases, it lowers the temperature profiles and at the same time at constant radial distance, increase in time, the temperature decreases. For skin friction, as the as stenotic height increases, the profiles of skin friction decreases.enArterial occlusionsComputational modellingThesis
