THE TURBULENT CONVECTIVE HEAT TRANSFER FOR AIR-WATER MIST FLOW ALONG A DRY ISOTHERMAL FLAT PLATE

本文报道了对含雾空气流过无液膜覆盖时等温干平板的湍流传热进行的理论分析与实验研究。所得到的半经验准则关系式经实验检验符合良好,可供工程上用以预估气流含雾对增强传热的效果。

A physical model with distributed heat sink and its mathematical description were given for the turbulent convective heat transfer of air-water mist flow along a dry isothermal flat plate. As the result of an approximate solution of the integral equations, a practical semi-empirical dimensionless relation was established successfully for predicting the convective heat transfer enhancing factor and checked well by eyperimental data.
