Application of temperature-sensitive paint with two channels for studying thermal processes in short duration gas dynamic facilities

Specialists from TsAGI have developed a unique two-channel luminescent transducer, a temperature-sensitive paint that allows the measurement of full-field surface heat transfer rates in short-duration wind tunnels. The paper contains a description of the features of the method, its advantages, as well as a brief review of several main results obtained in the study of complex heat transfer structures under high gas flow velocities.
