Flow in the cavity with heat generating body finds wide domestic and indust
rial applications. The heat transfer characteristics and the irreversibilit
y generated in the cavity depend on mainly the cavity site, aspect ratio of
the heat generating body, and inlet/exit port locations. In the present st
udy effect of exit port locations on the heat transfer characteristics and
irreversibility generation in a square cavity with heat generating body is
investigated A numerical simulation is carried out to predict the velocity
and temperature fields in the cavity. To examine the effect of solid body a
spect ratio on the heat transfer characteristics two extreme aspect ratios
(0.25 and 4.0) are considered in the analysis. Fifteen different locations
of exit port ave introduced while air is used as an environment in the cavi
ty. It is found that non-uniform cooling of the solid body occurs for exit
port location numbers of 13 and beyond In this case, hear transfer reduces
while irreversibility increases in the cavity. These findings ave valid for
both aspect ratios of the solid body.
