| Abstract: | An experimental method for determining the heat flux of a flow field is presented. The free turbulent air jet is investigated. The distributions of the velocity and the correlative fluctuation quantity of velocity as well as the temperature were measured with a single hot-wiremeter and a fine thermocouple and the distribution of the heat flux of the jet was calculated by the classical turbulent theory. A comparison of the measured results with calculated ones shows fairly good agreement. |
