Abstract :
The paper numerically studies the enclose with force and free heat convection. Galerkin finite element approach was used for the numerical analysis, the investigated enclosure are square geometry with an inlet at the bottom and an opposite outlet at the top. The heat was applied to one side of the enclosure while the other walls were set as an insulated wall. Reynolds number was changed during the test from 50 to 175 (50, 100, 150, and 175), Richardson number was changed during the test from 0 to 30 (0, 5, 10, 15, 20, 25, and 30). The Nusselt number was calculated along the heated wall and as an average value, it was found that as the Reynolds and Richardson numbers increases, the Nusselt number is also increased. The isothermal lines and the streamlines were illustrated for different Reynolds and Richardson numbers.
