Heat flux distribution and heat transfer coefficient distribution over a surface of a component used in a high temperature environment are determined by supplying coolant of predetermined characteristics to the component and measuring a temperature distribution over a predetermined surface. The heat flux at each temperature measurement point on the surface of the component is determined from heat flux calibration data obtained before the component is placed in service and while it is being operated at in-service cooling conditions. The heat transfer coefficient at various locations on the surface of the component is determined from the heat flux indicated by the heat flux calibration data, the temperature of the surface, and the temperature of the environment in which the component is situated.
