Catalytic surface reactions with variable properties and Casson nanofluid flow under variable thermal radiations

Flow over catalytic surfaces plays a crucial role in enhancing chemical reactions, with significant applications across various industries, including chemical processing, combustion systems, biochemical sectors, and engineering technologies. Using temperature-dependent thermal conductivity and thermal diffusivity, we examine how different types of catalytic surface reactions affect the behavior of Casson nanofluid flow in this work. In dimensionless terms, the governing dimensional PDEs are reduced to a framework of nonlinear ODE systems by introducing appropriate normalized parameters. We thereafter obtain the solutions to the equations using the Homotopy Analysis Method (HAM). Graphical and tabular results illustrate how various catalytic surface reactions affect velocity, temperature, and concentration distributions. According to the parametric analysis, stronger thermal and material transport is facilitated by thermal radiation, thermal conductivity, and thermal diffusivity. This results in more noticeable boundary layer effects and higher transfer rates.
