Abstract: A system and method for thermal inspection of a component having at least one cooling hole is disclosed, that uses an evaporative membrane for direct evaporative cooling of an exhausted working fluid. A working fluid is supplied to at least one internal passage of a component that is configured to exhaust the working fluid from the internal passage sequentially through the cooling holes and the wetted evaporative membrane disposed in direct air-tight contact with the component. An imager captures a time series of images corresponding to a transient evaporative response of the exhausted working fluid to determine a plurality of temperature values for the exhausted working fluid after passage through the evaporative membrane. A processor circuit is configured to evaluate the transient evaporative response of the exhausted working fluid.
