Local heat transfer coefficients on flat continuous, flat interrupted and corrugated external cooling fins

Abstract:

An experimental investigation into the performance of gas turbine engine component external cooling fins has been carried out using the transient liquid crystal technique in a low speed wind tunnel. Full fin surface local heat transfer coefficient distributions have been determined. Measurements with this level of resolution are not previously reported in the literature. In addition to the flat continuous fins, interrupted and corrugated fin geometries have been tested. These geometries enhan...
