英文摘要	Global heat flux measurement techniques with high spatial resolution are needed to accurately capture the peak heat flux and its location for the design of thermal protection system. However, background radiation from combustion presents an obstacle to the application of global heat flux measurement techniques. To solve this problem, a new method for heat flux determination suitable for strong combustion radiation environment is described. The core idea of this method is that heat flux on the inner surface of the combustor was identified by solving the three-dimensional transient inverse heat conduction problem while measuring the outer surface temperature using temperature-sensitive paint. Measurement system configuration, data processing method, and effect of layer thickness of the temperature-sensitive paint on the measurement results are introduced in detail. Finally, both numerical and experimental results are presented to demonstrate the validity of the new method.
