| Abstract | ||
| Laminar mixed convection flow in equilateral triangular lid-driven enclosure is numerically investigated by using ANSYS 12.1 program .The horizontal side wall is sliding from left to right with a hot temperature of (Th). The other two inclined walls are considered to be isothermal, cold and its temperature is (Tc). The governing equations (energy equation, momentum equation and continuity equation) are solved using the finite element method with ANSYS 12.1 program. The governing parameters are Grashof number (Gr =105,106 and 107) and Richardson number (Ri=0, 1, 10, 100). An air is used as a working fluid with Pr=0.71. The obtained results represent as isothermal contours and stream function. It is obvious from the result that, the motion of the sliding wall has a dramatic effect on the flow and temperature distribution more than the buoyancy force, and then has an effect on heat transfer. | ||
