Magnetized Casson hybrid nanofluid flow under the influence of surface-catalyzed reactions over a porous moving wedge
Source abstract
Abstract
The main finding of this work focuses on the numerical analysis of magnetized Casson hybrid nanofluid flow via porous moving wedge with surface-catalyzed reactions. Thermal radiation and chemical reactions are also investigated as heat and mass transport mechanisms. Feature of hybrid nanofluid, which contains nanoparticles, such as nickel zinc ferrite (NiZnFe2O4) and manganese zinc ferrite (MnZnFe2O4) nanoparticles with engine oil as a working fluid, is discussed. These hybrid nanofluids (NiZnFe2O4 + MnZnFe2O4/C2H18) offer significant improvements in thermal conductivity, heat transfer efficiency, and magnetic control, making them ideal for automotive, industrial, and magnetic fluid applications. The flow dynamics of the system have been modeled using a system of non-linear PDEs, which are transformed into dimensionless ODEs using appropriate similarity conversions. The transformed ODEs are solved using the fourth- and fifth-order Runge–Kutta–Fehlberg method along with the shooting technique. Results indicate that increased surface-catalyzed parameters in porous media accelerate heterogeneous catalysis, leading to more vigorous reactions and shorter reaction times. Furthermore, the incorporation of NiZnFe2O4 and MnZnFe2O4 nps in the base fluid substantially improves both the velocity and energy transmission rate. Engine oil containing ferrite nanoparticles on porous moving wedge could improve engine performance and efficiency in automotive cooling systems and lubrication effectiveness.
