INFLUENCE OF JOULE HEATING AND THERMAL RADIATION ON UNSTEADY HYDROMAGNETIC FLOW OF CHEMICALLY REACTING CASSON FLUID OVER AN INCLINED POROUS STRETCHING SHEET

In the present work, unsteady hydromagnetic flow of Casson fluid over an inclined permeable stretching sheet in the presence of Joule heating, thermal radiation, and chemical reaction is investigated. The governing flow equations are reduced to a system of nonlinear ordinary differential equations by using similarity transformations. The resulting system is solved numerically using the Runge-Kutta fourth-order technique along with the shooting method. Comparison shows that the present results are in excellent agreement with previous existing results. The impact of various physical parameters on flow variables has been discussed in detail. The result shows that the temperature increases with increasing applied magnetic field and thermal radiation parameter. Further, the concentration decreases for the case of a destructive chemical reaction while it increases for the case of a generative chemical reaction.
