COUPLED THERMAL RADIATION AND CHEMICAL REACTION EFFECTS ON HEAT-GENERATING CASSON FLUID FLOW OVER AN INCLINED OSCILLATING PLATE IN A ROTATING POROUS MEDIUM R. Raju A. Selvaraj L. Tamilselvi

The article examines unstable Magnetohydrodynamics (MHD) transfer of a Casson fluid by advection within a rotating porous medium. The flow occurs over an inclined plate characterized by transverse oscillations, variable surface temperature, and mass diffusion. The mathematical model accounts for the concurrent influences of radiant, generating heat or utilization within the system and first order chemical reactions. We applied Crank-Nicolson finite difference with Thomas algorithm to make nondimensionalize the governing equations and derive their solutions analytically. The numbers indicate that fluid velocity decreases as the inclination angle, magnetic parameter, radiation parameter, Prandtl number, Schmidt number, and chemical reaction parameter increase. On the other hand, it goes up when the thermal and solutal Grashof numbers and the heat source parameter go up. As the radiation and heat generation parameters go up, so does the temperature distribution. But as the Prandtl number goes up, the temperature distribution goes down. Additionally, the concentration profile decreases as the Schmidt number and chemical reaction parameter increase. This is because the mass diffusivity goes down and the chemical interaction gets stronger.
