Краткое описание

Experimental investigations of the influence of an external degree of turbulence on heat transfer intensification in a cavity with a small aspect ratio, with the angles of inclination of the lateral walls being varied from 30° to 90°, were carried out. It is shown that in a rectangular cavity the average heat-transfer rate over the surface at a turbulence level Tu0 of 6.5% increases by a factor of 1.2, whereas at Tu0 = 16% − by a factor of 1.4. The visualization of the patterns of vortex formation has shown that at angles φ = 60° or 70° the flow becomes extremely unstable, depending on the Reynolds number. For these angles one observes a marked enhancement of heat transfer which is strengthened at a high flow turbulence.
