Numerical simulation of non-stationary thermal and thermoelectric processes in a sensor on a heterogeneous structure of a copper-nickel pair for conditions behind a reflected shock wave and external supersonic flow around the body is carried out. Good agreement between electrical signals, volt-watt coefficient obtained in calculation and experiment is obtained. The heat flux calculated using the proposed method is close to the theoretical value. Keywords: sensor, shock tube, heat flux, measurement.
