FIELD: physics; measuring. ^ SUBSTANCE: invention concerns to field of thermophysical experiment. In the method prestressly change detail temperature in relation to temperature of medium, then carry out contact of a detail to a cooling medium, fix change in time of temperature of a detail. A cooling medium pump over through interior channels of a detail, ooze a wall device on an outside surface of a detail and fixation of change in temperature time carry out on this device of a detail by means of scanning infrared image converter and fixation carry out with the frequency equal to frequency of formation of a shot infrared image converter and spot coefficient of a convective heat exchange taking into account volume of the oozed device of a wall of a detail, the area interior heat-exchange surfaces of the oozed device, a difference of temperatures of an outside surface of the oozed device, fixed in two next shots and frequencies of formation of a shot infrared image converter. ^ EFFECT: increase of accuracy of determination of coefficient of a convective heat exchange. ^ 1 dwg |
