Thermodynamic and Magnetohydrodynamic Analysis of Blood Flow Considering Rotation of Micro-Particles of Blood

Flow and heat transfer of blood under the action of an external magnetic field are analyzed in this paper. The flow is considered to take place in a channel that is bounded by stretchable walls. The surface velocity of the channel is assumed to vary linearly with axial distance. The microrotation of the micro-particles of blood is taken into account by treating blood as a micropolar fluid. The governing partial differential equations are transformed into a system of ordinary differential equations and then solved numerically by developing a suitable finite difference technique. Computational work has been carried out in order to have an estimate of the velocity, microrotation, and the temperature of the fluid for different values of various physical parameters of interest in the present study of blood flow dynamics. Different physiological aspects are discussed via graphical presentation of the computed results.
