INFLUENCE OF CONVECTIVE BOUNDARY CONDITION ON NONLINEAR THERMAL CONVECTION FLOW OF A MICROPOLAR FLUID SATURATED POROUS MEDIUM WITH HOMOGENEOUS-HETEROGENEOUS REACTIONS

A numerical approach has been used to analyze the effects of homogeneous-heterogeneous reaction and nonlinear density temperature variation over a vertical plate in an incompressible micropolar fluid flow saturated Darcy porous medium. In addition, convective boundary condition is incorporated in a micropolar fluid model. The similarity representation for the set of partial differential equations is attained by applying Lie group transformations. The resulting non-dimensional equations are worked out numerically by spectral quasi-linearization method. Less temperature and wall couple stress coefficient, but more velocity, skin friction, species concentration, and heat transfer rate are noticed by enhancing the nonlinear convection parameter. It is also observed that as the strength of homogeneous and heterogeneous reaction parameters increases, the species concentration and mass transfer rate reduces.
