Magnetohydrodynamic mixed convective flow of micropolar fluid past a stretching surface using modified Fourier’s heat flux model

Abstract

The knowledge of heat transfer of MHD flows across a stretched surface plays a crucial role in transportation, heat exchangers, fibre coating, magnetic drug treatment, etc. The present research article delivers a numerical examination of 2D magnetohydrodynamic nonlinear radiative flow of micropolar fluid towards a stretching surface. The fluid motion is steady and laminar. The impacts of chemical reaction, cross-diffusion and thermal and solutal Biot numbers are deemed. Combined influence of heat and mass transfer attributes is investigated. For effective heat transfer, Cattaneo–Christov heat flux term is added to the energy equation. The appropriate transmutations are adopted for rehabilitating the flow governing PDEs into dimensionless ordinary ones. Further, these ODEs are resolved by R.K.F-4 with a shooting system. The graphs are plotted to picture the flow fields for the flow regulating parameters. The friction factor, couple stress and mass and thermal transport rates are presented for the flow relevant variables. From the results, we spotted that there are an enhancement in velocity but a decrement in temperature and concentration fields with the swelling in the values of primary slip parameter. Also the temperature and concentration fields are enhanced with the boosting values of Dufour and Soret numbers, respectively.
