ENTROPY GENERATION OF UNSTEADY RADIATIVE CASSON FLUID FLOW THROUGH POROUS MEDIUM OVER A PERMEABLE STRETCHING SURFACE WITH INCLINED MAGNETIC FIELD

Present paper aims to investigate entropy generation of unsteady radiative Casson fluid flow through porous medium over a permeable stretching surface with inclined magnetic field. Time-dependent partial differential equations are transformed into non-linear ordinary differential equations using similarity transformations. These transformed equations are solved numerically by Runge–Kutta fourth-order with shooting technique. The effects of pertinent parameter such as magnetic field parameter, Casson fluid parameter, inclined angle of magnetic field parameter, Radiation parameter and Reynolds number on the velocity, temperature and entropy profiles are presented graphically. Local Nusselt and local Sherwood number are also obtained and presented in tabulated form.
