Heat and Mass Transfer Performance of Dufour and Heat Source on Casson Fluid Flow Past an Inclined Oscillating Rotating Porous Plate with Chemical Reactions and Thermal Radiation

The current research presents an analytical interpretation of unsteady-free convective hydromagnetic boundary layers, focusing on how the Dufour effect, thermal radiation, and chemical reactions influence Casson fluid flow through a rotating porous medium, around an inclined oscillating platewithin a uniformfield. The governing equations are solved using the Laplace transform method, with the results presented visually through numerical values of Casson fluid velocity, temperature, and concentration at the plate, based on various key parameter values. The study examines how the Casson fluid behaves compared to Newtonian fluid, with the Casson fluid demonstrating a higher velocity. The findings also show that, as temperature decreases, parameters such as the Grashof number, Dufour effect, thermal radiation parameter (R), and chemical reaction parameter (K) increase. Additionally, increasing the chemical reaction parameter (K) causes a reduction in concentration. In analyzing the fluid flow, the study also measured the influence of Prandtl, Schmidt, thermal, and Grashof numbers. The results indicate that the velocity of the fluid decreases with higher radiation levels, but increases when the heat source and Grashof number are elevated. Similarly, rising radiation levels reduce temperature, while a stronger heat source increases it.
