A NUMERICAL STUDY ON MHD FLOW OF A CASSON FLUID PASSING THROUGH A VERTICAL CONE WITH SUCTION VELOCITY AND THERMO-DIFFUSIVE EFFECTS.

Abstract

A mathematical model is developed for an unsteady MHD flow of a Casson fluid passing through a vertical cone with the effect of chemical reaction, thermal radiation, thermos-diffusive ef-fects and additionally with the influence of suction velocity. The non-dimensional governing equation of the fluid problem are solved numerically by fi-nite difference method. Numerical solution of ve-locity, temperature, and concentration along with the influence of different parameters are obtained and their nature is described graphically. The re-sults of the study indicate a considerable effect of parameters on velocity, temperature, concentra-tion. The rate of heat and mass transfer along with skin friction has also been influence by the existing parameters.
