Radiation and heat absorption effects on an unsteady MHD boundary layer flow along an accelerated infinite vertical plate with ramped plate temperature in the existence of slip condition

A numerical analysis of an unsteady MHD laminar boundary layer flow over an accelerated moving vertical plate along with ramped temperature was performed, in which chemical reaction, heat absorption, and radiation were considered. Slip circumstances have sparked much concern, because of its widespread application in chemical engineering and manufacturing industries. The equations of momentum, thermal, and as well as species concentration, were solved numerically by implementing the Crank–Nicholson scheme. There is a visual representation of changes in fluid velocity, temperature, and concentration, the numerical values of drag force, Nusselt, and Sherwood numbers are provided in tabular form for various values of field variables. Results show that slip condition has a considerable impact on a small intensity of λ, and that this effect is extra pronounced in the steady condition than in the ramped condition. Profiles of velocity and temperature are reducing in both cases for increased values of heat absorption and magnetic field parameters.
