The pulsatile flow of thermally developed non-Newtonian Casson fluid in a channel with constricted walls

This article presents a numerical investigation of the pulsatile flow non-Newtonian Casson fluid through rectangular channel with symmetrical local constriction on walls. The objective is to study heat transfer characteristics said under an applied magnetic field and thermal radiation. Such may find its application in devising treatments for stenosis blood arteries, designing biomechanical devices, controlling industrial processes pulsation. Using finite difference approach, mathematical model solved converted into vorticity-stream function form. impacts Hartman number, Strouhal parameter, porosity Prandtl radiation parameter profiles are argued. effects axial velocity temperature observed Some plots streamlines, vorticity, distribution also shown. On increasing values increases, whereas decreases. have similar trend, opposite trend parameter. decreases increase number. increases profile patterns not perfectly uniform downstream constriction.
