본 연구에서는 상기 연구의 연장으로서 Prandtl수가 6.05인 내부발열유체가 경사진 정사각 난류자연대류유동, 온도분포 및 열전달량의 분포를 수치적인 방법으로 예측하였다. 벽면 깅이의 1/2를 특성길이로 하는 Rayleigh수의 범위는 1*$10^{6}$ ~1*$10^{9}$ 으로 선택하였으며 경사각도는 0˚, 15˚, 30˚및 45˚로 선택하였다.
A numerical analysis was carried out to study two-dimensional turbulent natural convection in a square enclosure containing fluid of Prandtl number 6.05 within internal energy sources. The square enclosure was bounded by four rigid planes of constant equal temperature. Inclination angles of 0, 15, 30 and 45 deg. from the horizon for Rayleigh numbers from 1 * 10$^{6}$ to 1 * 10$^{9}$ were studied. Local and average Nusselts numbers are obtained on all four walls. If inclination angle exists, the average Nusselt number appears in increasing order at bottom, left, right and top wall.
