چکیده
In this study, mixed convection heat transfer and local and global entropy generation in a
ventilated square cavity have been investigated numerically. The natural convection effect is
achieved by a constant heat flux imposed at the bottom wall and cooled by injecting a cold
follow. In order to investigate the effect of port location, four different placement
configurations of the inlet and outlet ports are studied. In each case, external flow enters into
the cavity through an inlet port in the left side of the cavity and exits from the opposite side.
The other boundaries are assumed adiabatic. The cavity is subjected to laminar flow of water.
The investigation has been carried out for the Re=1000, and the Richardson number with the
range of 0.0001(Global Entropy Generation), Heat Transfer Irreversibility (HTI) and Fluid Friction
Irreversibility (FFI) are calculated and compared. Then, the optimum inlet/outlet configuration
has been selected based on the minimum GEG and the maximum heat transfer.
