It is imperative to develop the quantitative analysis describing fin-tube

管外轧肋以强化凝结换热的方法应用得非常广泛,但定量描述这一强化过程的理论工作还远远落后于其应用程度.本文从肋管强化凝结换热的机理着手,经过细致的理论分析,对Borovkov 模型作了两个方面的修正:一是肋峰区与肋谷区凝结液压力差项的确定;另一是水平肋管底部凝结液附着区域的求取方法.从而建立起全面描述水平肋管外凝结换热的理论模型,并进行了求解.修正后的模型较原模型更加合理完善.为验证理论工作的准确程度,通过实验测定了平均凝结换热系数,并与理论计算值作了比较,比较结果基本令人满意.

Theoretical studies have been made on the laminar convective heat transfer from an isothermal vertical flat plate in an airwater mist flow. Based upon the present authors experiments, an analytical model is given. In this paper the heat transfer boundary layer equations are solved by the Van Dyke's Matching Method, which is one of the singular perturbation methods. A theoretical relation of heat transfer from an isothermal vertical flat plate in two phase mist flow has been obtained. This relation explained clearly what is the key mechanism influencing heat transfer. The present results can be used for industrial design purposes.
