MHD mixed convection boundary layer flow of a Casson fluid bounded by permeable shrinking sheet with exponential variation

A review was carried out on the exponentially permeable shrinking sheet on how it influenced the magnetohydrodynamic (MHD) mixed convection boundary layer flow of a Casson fluid. The boundary layer equations in the form of partial differential equations have been transformed to the ordinary differential equations, by using the similarity transformation. Subsequently, the numerical technique uses the shooting way to provide solutions for the ordinary differential equations. Different factors related to the flow and heat are indicated by the attained results as well as graphs. Moreover, four solutions are presented graphically. Also, the numerical calculations exhibit that the Casson fluid parameter ε, buoyancy parameterλ and suction parameter s would significantly affect the characteristics of flow and thermal boundary layers of a Casson fluid.
