Motion of Casson-Williamson with MHD Chemically Reacting Nanofluids under the Influence of Nonlinear Buoyancy Force and Theories of Cattaneo-Christov

The focus of this research is to examine the Cattaneo-Christov heat and mass transfer processes on Casson-Williamson fluids with nonlinear buoyancy force and thermal radiation. The flow analysis was described by partial differential equations (PDEs). The resulting PDEs were simplified by utilizing suitable variables to derive coupled nonlinear total differential equations. Spectral homotopy analysis method (SHAM) was employed to solve the simplified equations. SHAM is the connections of Chebyshev differential matrix and homotopy analysis method (HAM). This research is unique because it addressed nonlinear buoyancy force significance on Casson-Williamson with Cattaneo-Christov theories with Soret-Dufour, thermal radiation, viscous dissipation, magnetic field parameter and chemical reaction. A higher Casson parameter (β) is observed to reduce the fluid velocity due to higher plastic dynamic viscosity. Increase in nonlinear buoyancy parameter for both temperature and concentration are noticed to enhance the fluid velocity.
