Effect of Applied Magnetic Field on Pulsatile Flow of Blood in a Porous Channel

An approximate solution is presented to the problem of pulsatile flow of blood in porous channel in presence of induced magnetic field. The blood is assumed to be an incompressible Non Newtonian fluid. To reduce the equation of motion to an ordinary differential equation, a dimensionless variable is used. Numerical results were obtained for different values of the magnetic parameter, frequency parameter and Reynolds number. It is observed that when the magnetic parameter, the Hartmann number increases, the velocity as well as magnitude of mass flux decreases. For non magnetic case the paper reduces to the problem investigated by Wang
