Fluorescent paint for measurement of heat transfer in shock - turbulent boundary layer interaction

The principles of the fluorescent paint technique for surface heat transfer measurement are presented. This technique allows determination of the heat transfer from a surface with good accuracy and high spatial resolution. To examine the capabilities of this technique, the temperature-sensitive paint is used to visualize and measure heat transfer in several typical shock-turbulent boundary layer interactions. Quantitative comparison of the measured heat transfer with existing data obtained using conventional methods is discussed.
