In this paper investigates the heat exchange of the high-temperature surface of the working area during cooling by a dispersed two-component flow. A brief description of the experimental stand, the working section of the spraying device for creating a dispersed flow is given. The results of experimental modeling of the cooling of the working section at different regime parameters of the flow and supplied electric powers are presented. Data on the distribution of the wall temperature along the length of the heated working section are obtained. The thermal flux density on the side surface of the working area was estimated based on the readings of thermocouples in the work area. The operating parameters of the coolant at which the sample is cooled most effectively are determined.
