A Method for Correcting Measurements of the Heat Transfer Factor through the Skin of a Wind Tunnel Model

摘要

In an experiment in which it is required to measure the heat transfer factor at the outer surface of the skin of a wind tunnel model, the temperature of the skin is measured at various points on this surface and the heat flow rate across the skin is measured at the corresponding points on the inner surface. Calculation of the heat flow rate across the outer surface of the skin involves the solution of Laplace's equation in a rectangular region with mixed boundary conditions. A numerical method of solution is described and illustrated by an example.
