Effects of activation energy and chemical reaction on unsteady MHD dissipative Darcy-Forchheimer squeezed flow of Casson fluid over horizontal channel. | LitMetric

AI Article Synopsis

  • The study investigates how chemical reactions and activation energy affect the flow of magnetohydrodynamic Casson fluids in a porous medium, particularly in settings like nuclear reactors and vehicles.
  • By converting partial differential equations into ordinary differential equations using similarity variables, the study employs MATLAB for numerical analysis to examine fluid velocity, thermal distribution, and concentration.
  • Results show that bringing the parallel plates closer increases fluid velocity and temperature, while higher Hartmann numbers decrease velocity due to strong Lorentz forces, and increased Darcy-Forchheimer and activation energy parameters reduce both velocity and concentration.

Article Abstract

The impact of chemical reaction and activation energy plays a vital role in the analysis of fluid dynamics and its thermal properties. The application of the flow of fluid is significantly considered in nuclear reactors, automobiles, manufacturing setups, electronic appliances etc. This study explores the impacts of activation energy and chemical reaction on the magnetohydrodynamic Darcy-Forchheimer squeezed Casson fluid flow through a porous material across the horizontal channel where the two parallel plates are assumed to be in motion. By using similarity variables, partial differential equations are converted to ordinary differential equations. Numerical method is applied using MATLAB to solve the problems and acquire the data for velocity field, thermal distribution, and concentration distribution. The graphs indicate that fluid velocity and temperature increases as the plates are brought closer. In addition, there was a correlation between a rise in the Hartmann number and a decrease in the fluid's velocity 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 decreases.
