An efficient method for solving large scale unconstrained optimization problems is the conjugate method. Based on the conjugate gradient algorithm proposed by Rivaie, Mohd, et al. ("A new class of nonlinear conjugate gradient coefficients with global convergence properties." Applied Mathematics and Computation 218.22 (2012): 11323-11332.), we propo...

This paper deals with the numerical investigation of simultaneous heat and mass transfer flow of a viscous, incompressible and radiating fluid along a vertical channel in a porous medium. The non-linear equations governing the flow for heat and mass transfer are solved by using a very efficient numerical scheme of Runge-Kutta Fehlberg fourth fifth...

The aim of the present study is to investigate the effect of flow parameters on the free convection and mass transfer of an unsteady magnetohydrodynamic flow of an electrically conducting, viscous and incompressible fluid past an infinite vertical porous plate in the presence of variable suction. The thermal radiation and chemical reaction effects...

This paper presents the study of the effects of variable thermal conductivity and Darcy-Forchheimer on magnetohydrodynamic free convective flow in a vertical channel in the presence of constant suction. The resulting governing equations are non-dimensionalised, simplified and solved using Crank Nicolson type of finite difference method. To check th...

The present paper investigates the combined effects of Soret and Dufour on free convective heat and mass transfer on the unsteady one-dimensional boundary layer flow over a vertical channel in the presence of viscous dissipation and constant suction. The governing partial differential equations are solved numerically using the implicit Crank-Nicols...

The study of convective heat and mass transfer flow over a vertical plate with nth order chemical reaction in a porous medium is analyzed both analytically and numerically. The resulting governing boundary layer equations are highly non-linear and coupled form of partial differential equations and have been solved by using implicit finite differenc...

This paper investigates the study of the effect of thermal conductivity on MHD flow past an infinite vertical plate with Soret and Dufour effects. The governing non-linear Partial Differential Equations are solved numerically by implicit finite difference scheme of Crank-Nicolson. Computations are performed for a wide range of the governing flow pa...
