AB A numerical study of air-filled slowly rotating enclosure with three rows of discrete heat sources is made. The enclosure rotates around its longitudinal horizontal axis. Three physically realizable phenomena, uniperiodic oscillation, multiperiodic oscillation, and chaotic oscillation are identified numerically. In the cases of stationary or low rotation speed, buoyancy force causes clockwise and counterclockwise circulations, and correspondingly there are three or two local peak Nusselt numbers in each periodic oscillation. With increasing rotation, clockwise circulation is enlarged and tends to dominate the counterclockwise circulation. The second and third peak Nusselt numbers become weakened and negligible. In a stationary case, heat transfer behavior for the heaters of the top row and bottom row is symmetrical, but with an increase in the speed of rotation, it gradually becomes asymmetrical.
