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

A review was carried out on the exponentially permeable shrinking sheet and how it in uenced the magnetohydrodynamic (MHD) mixed convection boundary layer flow of a Casson fluid. The boundary layer equations in the form of partial differential equations were transformed into the ordinary differential equations by using the similarity transformation. Subsequently, shooting technique is used to provide solutions for the ordinary differential equations. Different factors related to the ow and heat are indicated by the attained results as well as graphs. Moreover, 4 solutions are presented graphically. Also, the numerical calculations exhibit that the Casson uid parameter, ", buoyancy parameter, , and suction parameter, s, would signicantly affect the characteristics of ow and thermal boundary layers of a Casson fluid.
