I have a set up which is basically a small wind tunnel (single rectangular channel) with an axial fan at the inlet. The experiment is testing the effect of various shaped "shrouds" that constrict flow around an inductor to improve the convective cooling. I have heat transfer coefficients and pressure drops gathered from the different shroud concepts, but I need some sort of measure of performance to evaluate them. Would plotting HTC versus power consumed by the fan by an effective way to do this? The goal here is to minimize fan power but maximize the heat transfer.
