The exclusive impact of Hall current over a variably thicked sheet in magnetized viscous fluid by the implementation of non-Fourier flux theory

Abstract

Present study carried out the speculative investigation of Hall current effects on MHD viscous fluid flow over stretching sheet with variable thickness. For heat transfer analysis, Christov–Cattaneo heat flux model is used instead of classical Fourier law. The mathematical formulation of current flow configuration yields the set of partial differential equations with higher order of nonlinearity. The modeled partial differential equations are switched into ordinary differential equations with the aid of an appropriate set of local similarity transforms. The resulting similarity equations are tackled numerically with the assistance of fifth order Runge–Kutta integration scheme. The expressions for axial velocity, transverse velocity and temperature are numerically computed and analyzed against variations in the controlling parameters with the help of graphs. To insight flow behavior in the neighbourer region of sheet surface, local skin friction coefficients and local Nusselt number are calculated. The effects of involving flow parameters on these interesting quantities are elaborated through tabular representations. A suitable correlation of current results with previously reported data (in limiting case) is presented for the validation of computed results.
