ABSTRAKT

A numerical investigation is presented for fluid flow and heat transfer of an electrically conductive liquid in a square cavity. In this work, the right wall of the cavity is kept at a high constant temperature, and the others are at low uniform temperature. The cool walls and the fluid are heated by both convection and radiation. The motion of the fluid is described by continuity equation and momentum equation which are solved by artificial compressibility algorithm based on finite volume method (FVM). The heat transfer of the fluid along with the walls is described by energy equation and radiative transfer equation (RTE) which are solved by FVM and discrete ordinates method (DOM) respectively. New dimensionless number A and B are obtained by dimensional analysis of governing equations. Investigations are performed with different A number and Ha number. The results show that radiation has remarkable effects on fluid flow and heat transfer under different values of parameters.
