“…He embraced the Galerkein finite element scheme in solving the problem and infers that velocity distribution rises as hall and Grashof parameters of thermal and concentration transmissions also intensify. Venkateswarlu et al [25] studied the role of mass transport on nonlinear MHD boundary layer flow of a viscid non-compressible fluid along a nonlinear leaky elastic plate in a permeable medium with heat source. Numerically, Bilal and Nazeer [26] investigated the non-Newtonian flow along a stratified elastic/lessening inclined plate due to an associated magnetic field and nonlinear convective flow.…”

The examination of nano-fluid in recent time has been encouraging just as its research interest cuts across some disciplines such as mathematics, mechanical, chemical, civil engineering, physics, earth and natural sciences. Its applicability in the industrial and technological advancement helps in controlling the rate at which heat is conducted and diffuses in a given medium, as well as improving thermal transportation through convection, radiation and conduction. In this work, the analysis of hydromagnetic nano-fluid flow past an inclined heated surface with temperature dependent non-uniform heat source/sink and thermal radiation under heat and mass transmission perspective is considered. Adequate similarity variables are employed in recovering the nonlinear coupled ordinary differential equations (ODEs) from the partial differential equations (PDEs) which describe the equation of the boundary layer. The transformed equations (ODEs) are addressed both analytically and numerically with the aid of regular series approximation technique and Wolfram Mathematica package. The numerically simulated obtained results are graphically presented with legends. The computations opined that velocity declines while energy increases as the magnetic field number enhances. Similarly, improvement on angle of inclination, breeds velocity deceleration. Furthermore, the rate of energy transfer increases as the temperature dependent non-uniform parameters due to thermal generation enhances. In addition, the nanoparticle concentration decreases with increasing values of Schmidt and thermal radiation factors.

The present investigation deals with the effect of slip on the hydromagnetic pulsatile flow through a parallel plate channel filled with saturated porous medium. Based on the pulsatile flow nature, the transformed conservation equations are solved analytically subject to physically appropriate boundary conditions by using two term perturbation technique. Exact solutions are obtained for the velocity, temperature and concentration fields. In particular skin friction coefficient, Nusselt number and Sherwood number are found to evolve into their steady state case in the large time

ABSTRACT. The heat and mass transfer characteristics of the unsteady hydromagnetic natural convection flow with Hall current and Soret effect of an incompressible, viscous, electrically conducting, heat absorbing and optically thin radiating fluid flow past a suddenly started vertical infinite plate through fluid saturated porous medium in a rotating environment are taken into account in this paper. Derivations of exact analytical solutions are aimed under different physical properties. The velocity, concentration and temperature profiles, Sherwood number and Nusselt number are easily examined and discussed via the closed forms obtained. Soret effect and permeability parameter tends to accelerate primary and secondary fluid velocities whereas hall current, radiation and heat absorption have reverse effect on it. Radiation and heat absorption have tendency to enhance rate of heat transfer at the plate. The results obtained here may be further used to verify the validity of obtained numerical solutions for more complicated transient free convection fluid flow problems.
