AbstractThe aim of the present paper is to study the influence of Hall current and Joule heating on flow, heat and mass transfer over an exponentially stretching sheet in a viscous fluid. Using similarity transformations the governing nonlinear coupled equations are converted into ordinary differential equations. These equations are linearized using the successive linearization method and then solved using the Chebyshev pseudo spectral method. The influence of magnetic parameter, Hall parameter, suction/injection parameter and slip parameter on the physical quantities are presented graphically. The obtained results are compared with the previously published results for special cases.

A theoretical study on the boundary layer flow of nanofluid past a bi-directional exponentially stretching sheet is presented. Heat transfer analysis via convective boundary conditions is performed. Further, the recently proposed boundary condition by Kuznetsov and Nield (Int. J. Therm. Sci. 77, 126 (2014)) is considered, which requires nanoparticle volume fraction at the wall to be passively rather than actively controlled. The resultant boundary layer equations are non-dimensionalized and then solved for the numerical solutions. The results are found in excellent agreement with the existing studies in the literature. It is seen that the thermal boundary layer is largely influenced by the variations in the convective heating at the sheet. Moreover the nanoparticle volume fraction is found to be in the vicinity of the bounding surface.

An attempt has been made to study the heat and mass transfer effect in a boundary layer MHD flow of an electrically conducting viscous fluid subject to transverse magnetic field on an exponentially stretching sheet through porous medium. The effect of thermal radiation and heat source/sink has also been discussed in this paper. The governing nonlinear partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations and then solved numerically using a fourth-order Runge-Kutta method with a shooting technique. Graphical results are displayed for nondimensional velocity, temperature, and concentration profiles while numerical values of the skin friction local Nusselt number and Sherwood number are presented in tabular form for various values of parameters controlling the flow system.
