A large scale modelling technique is developed to examine the effects of perforation geometry on the heat transfer and friction loss performance of compact heat exchanger fins. The cores were tested in a subsonic wind tunnel designed specifically for testing automobile radiators, environmental system condensers, and liquid-to-air heat exchangers. The plate surface porosity, the core frontal porosity, and the perforation size and arrangement were varied. The Reynolds numbers ranged from those corresponding to both laminar and turbulent flow. The heat transfer factor (j), friction fractor (f) and their ratio (f/j) for a single plate-channel system are obtained as functions of the Reynolds number, the plate surface porosity and the core frontal porosity. These results represent qualitatively those of a compact plate-fin heat exchanger having the same geometric scaling factors when these systems are represented by appropriate geometric, dynamic and thermodynamic similarity parameters.
