Abstract In the present paper, a numerical model is developed to examine the effects of chemical reaction on heat and mass transfer flow of a magneto-micropolar fluid over a non-conducting wedge with Hall and Ion-slip currents. The governing system of partial differential equations converted into similarity equations in ordinary differential equations by using the similarity transformations. The resulting equations thus obtained have been solved by adaptive Runge-Kutta method along with the shooting method. The effects of different physical parameters on velocity, microrotation, temperature and concentration distributions have been illustrated graphically. Also, the results for the skin-friction coefficient, the heat transfer rate and the mass transfer rate at the surface are tabulated for various values of fluid properties and the flow conditions. Numerical results show that the mass transfer rate increase with the Schmidt number and chemical reaction parameter. Keywords: Chemical reaction, Hall current, Heat and mass transfer, Ion slip, Micropolar fluids, Wedge.

Introduction The micropolar fluids are those Non-newtonian fluids, which contains particles of micro-size and they belong to a class of fluids with non-symmetric stress tensor that we shall call polar fluids. The presence of microstructure particles and non-symmetric stress can changed the hydrodynamics of the flow. The classical Navier-Stokes theory is not able to describe the flow properties of micropolar fluids e.g. exotic lubricants, biological fluids, colloidal suspensions, polymeric fluids, liquid crystals, animal blood and fluids containing certain additives. Eringen [1, 2 & 3] and Łukaszewicz [4] have provided detail discussion of the micropolar fluid and their application in fluid dynamics. The natural convection boundary layer flow of a thermo-micropolar fluid past a non-isothermal vertical plate has been studied by Jena and Mathur [5]. Beg et al. [6] investigated convective heat and mass transfer of micropolar fluids in a non-Darcy porous regime. Kumar [7] analyzed the problem of MHD mixed convective flow of a micropolar fluid. Pal and Chatterjee [8] have proposed a numerical model to examine the mixed convection magneto-hydrodynamic heat and mass transfer in micropolar fluid saturated Darcian porous medium. Recently, researchers [9-11] have been investigated micropolar fluid flow in various cases. The study of MHD micropolar fluid flow and heat transfer in presence of hall and ion-slip currents has important application in engineering and science e.g. in power generators, MHD accelerators, refrigeration coils, transmission lines, heating elements and electric transformers.
