Abstract

Conduction-combined forced and natural convection heat transfer flow of air in a differentially heated lid-driven parallelogram-shaped enclosure divided by a solid partition has been formulated and solved numerically using the finite-volume method with the SIMPLE algorithm. For the two-dimensional problem, numerical solutions are obtained for a wide range of Richardson numbers (0.1 ≤Ri ≤ 10), inclination angles of enclosure from the vertical direction (-60° ≤Φ≤ 60°), and thermal conductivity ratios (0.001 ≤K ≤ 10). The results indicate that all of the studied parameters and direction of moving lid have significant effects on Nusselt number and the average skin friction coefficient.
