Unsteady Free Convection MHD Flow over a Vertical Cone in Porous Media with Variable Heat and Mass Flux in Presence of Chemical Reaction

Abstract

This paper investigated unsteady free convection MHD flow over a vertical cone in porous media with variable heat and mass flux in presence of chemical reaction. Appropriate non-dimensional variables are used to reduce the dimensional governing equations that consists of continuity, momentum, energy, and concentration equations along with imposed initial and boundary conditions. The purpose of the study is to investigate this unsteady MHD flow problem using Crank-Nicolson method. The discretization equations were computed, and numerical results were plotted using MATLAB software. Numerical Results for the velocity, temperature and concentration profiles are presented graphically and discussed for different values of the physical parameters to show interesting features of the solutions. The result showed that the velocity profile increases when porosity and buoyancy ratio parameters are escalated, while an opposite behavior is notice against magnetic parameter and chemical reaction parameter.
