Abstract

In the present study, temperature measurements and flow visualizations are conducted to investigate the combined conduction, natural convection and radiation heat transfer in vented compact enclosures with a discrete heat source mounted on a vertical substrate attached to an enclosure wall. Effects of varying power levels (Q), opening sizes (Sv), aspect ratios (AR) and vent configurations are studied. Significantly different flow patterns are observed for variable vent configurations examined. Interactions among S„, AR, Q, and vent configurations are found to effect the flows prominently, however, the component temperatures are only slightly affected by the vent shapes for fixed opening area ratios. Enhancement of heat transfer due to venting is found to depend on the aspect ratios of the enclosures.
