Dynamics of mixed convection and Hall current in radiative power-law velocity slip flow of non-Newtonian fluid

Abstract

The present research letter aims to highlight the incompressible, laminar, two-dimensional electrical convoying flow of power-law material subject to the exponentially stretched sheet. Power-law velocity slip conditions are accounted. Hall current, radiative heat flux, transverse magnetic field, and dissipation effects are considered in the mathematical modeling. Radiative heat flux is defined in the presence of Rosseland’s diffusion model. Heat and mass transfer rates are discussed. The governing nonlinear derivation satisfying the flow is altered into nonlinear ordinary ones by the implementation of similarity quantities. The obtained nonlinear ordinary ones system is tackled numerically through the bvp4c technique. The resultant outcomes are calculated for various variables in tabular form and graphical demonstration for perfect consideration of the thermo-physical quantities. The considered model is discussed for two important fluids i.e. pseudo-plastic fluid (n = 0.7) and dilatant fluid (n = 1.3), and its primary and secondary velocities, concentration, and temperature fields are analyzed for emerging variables. The derived results are verified with limiting literatures by Shamshuddin et al. [4] and Saleem and El-Aziz [6] and found a 99.99 percent good agreement for the Newtonian case. Sherwood number, skin friction coefficient, and Nusselt number are computed for various emerging parameters.
