Electromagnetohydrodynamic Micropolar-Casson Fluid Boundary Layer Flow and Heat Transfer over a Stretching Material Featuring Temperature-Based Thermophysical Properties in a Porous Medium
This study investigates the boundary layer flow and heat transfer analysis in an electromagnetohydrodynamic dissipative micropolar-Casson fluid over a two-dimensional stretching sheet in porous medium. The physical model comprises the impact of thermal radiation, suction/injection,
temperature-dependent thermophysical properties (viscosity and thermal conductivity) associated with prescribed surface temperature condition. Appropriate similarity transformation variables are employed to redefine the governing equations from partial into ordinary differential equations while the resultant
equations are solved by shooting technique cum Runge-Kutta Fehlberg integration algorithm. The reactions of the physical parameters on the dimensionless quantities are presented through various graphs and tables. From the investigation, it is found out that the skin friction coefficient reduces with growth
in the micropolar material and in the presence of electric field terms whereas an opposite trend occurs with a rise in the Casson fluid material and magnetic field terms. More so, there is an increase in the thermal and hydrodynamic boundary layer due to a rise in the electric field and micropolar fluid material parameter. The obtained data in the current study also agree well with existing studies in literature under some limiting conditions.
