Magnetohydrodynamic Darcy-Forchheimer Squeezed Flow of Casson Nanofluid Over Horizontal Channel with Activation Energy and Thermal Radiation
The most well-known research areas in computational fluid dynamics are concerned with the interplay of fluid flow with chemical reaction and activation energy. According to the findings of several studies, its industrial applications include simulating the flow inside a nuclear reactor, for which it has received appreciation from many researchers. This study, driven by the use of flow in industrial challenges, explores the impacts of activation energy and chemical reaction on the magnetohydrodynamic (MHD) Darcy–Forchheimer squeezed Casson fluid flow through a porous material across the horizontal channel. The flow is produced when two horizontal plates are compressed to create more space between them. By using similarity variables, one may successfully convert partial differential equations (PDEs) to ordinary differential equations (ODEs). The shooting technique was used to carry out the numerical analysis, which entailed solving the competent governing equations with dominating parameters for a thin liquid layer. This was done to determine the results of the study. To validate the current solutions, it is vital to evaluate the numerical findings alongside the results of the prior research. The findings indicate that fluid velocity and temperature increases may be expected as the plates are brought closer together. In addition, there was a correlation between a rise in the Hartmann number and a decrease in the fluid’s velocity and concentration because of the existence of strong Lorentz forces. The temperature and the concentration of the liquid will increase due to the Brownian motion. When the Darcy–Forchheimer and activation energy parameters are both increased, the velocity and concentration decrease.
