摘要

Ceramic nanomaterials generally have valuable applications in insulation, air filtration, sound absorption, and catalytic processes. Understanding and modifying the behavior of fluids involved in these applications is therefore crucial; however, this has not been sufficiently elucidated in the literature. This study examines the effects of catalytic surface reaction and thermal radiation on the flow of a ceramic-based hybrid nanofluid over selected geometries. The flow problem is modeled using a system of governing partial differential equations, which are transformed into ordinary differential equations via similarity transformations. Numerical solutions are obtained using the MATLAB solver bvp5c, based on a finite-difference collocation method. The results indicate that increasing the catalytic reaction parameter enhances the fluid temperature while reducing both temperature and concentration gradients. Furthermore, increases in the fluid parameter and thermal buoyancy significantly enhance the velocity field. The ceramic nanoparticles and catalytic surface reactions considered in this study demonstrate improved flow behavior and enhanced heat transfer characteristics suitable for industrial and manufacturing applications.
