摘要
本文给出一种在用单热线和热偶测量流场有关参数的基础上利用湍流经典理论计算流场热流量分布的方法,并在对自由湍流射流实际测量与计算后与理论结果进行了比较,表明了该方法的准确性与可行性.
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.
