Abstract
The magnetohydrodynamics boundary layer flow of a Casson fluid in rotating frame through porous medium caused by exponentially stretching surface is studied numerically in this piece of research. To investigate the transport properties of thermal and solutal energy, the phenomenon of relaxation time for thermal waves with chemical reaction effects is incorporated. Additionally, the bio-convection and process of stratification is also supposed in energy transport mechanism. The numerical outcomes of the problem presented graphically are obtained against the variation in physical constraints. The resistance to fluid motion improves as the Casson parameter is increased in its magnitude, therefore, the flow field is reduced. The higher values of thermal relaxation time slow down the heat waves propagation.
