Apparatus and method for determining heat transfer coefficient based on testing actual hardware rather than simplistic scale models of such hardware


The heat transfer coefficient distribution on the surface of a component is measured by removing a predetermined amount of material from the surface of the component and replacing it with an insert comprising a layer of low thermal conductivity material, an array of temperature sensors, and a heater. The heat transfer coefficient is determined by applying a known amount of heat flux to the component by way of the heater and sensing the outputs of the temperature sensors. This procedure is carried out on actual hardware rather than on simplistic scale models of hardware.
