• VISCOUS DISSIPATION EFFECTS ON UNSTEADY HYDROMAGNETIC GAS FLOW ALONG AN INCLINED PLANE WITH INDIRECT NATURAL CONVECTION IN THE PRESENCE OF THERMAL RADIATION

Abstract

In this paper, the viscous dissipation effects on unsteady gravity-driven thermal convection flow of a viscous incompressible, electrically-conducting, absorbing-emitting, optically-thick gray gas along an inclined plane in the presence of thermal radiation has been carried out. The Rossel and diffusion flux model is employed to simulate thermal radiation effects. The governing equations for this investigation are solved numerically by using Ritz FEM. The effects of Prandtl number  Boltzmann-Rosseland radiation parameter  Hartmann number squared  Eckert number  Grashof number and plate inclination on the dimensionless velocity   and temperature  distributions are studied. Results obtained show that a decrease in the velocity and temperature distributions as the Prandtl number increased. The velocity and temperature are enhanced as Boltzmann-Rosseland radiation parameter and Grashof number are increased.
