摘要：
To measure the flow rate of coolant through a cooling hole of a film-cooled part, a transient thermal response of an external surface temperature of the film-cooled part is measured and the transient thermal response is characterized mathematically. From the mathematical characterization, the flow rate through the film hole is determined.
