考虑流体湿润性影响的核沸腾Rohsenow修正模型

A REVISION ON ROHSENOW MODEL FOR NUCLEATE BOILING OF LIQUID WITH CONSIDERING THE EFFECT OF SURFACE WETTABILITY

添加界面活性剂的核沸腾在改变蒸气泡生长特性的同时，主要是强化了对流换热．本文考虑流体湿润性影响，对核沸腾换热沿用最广的对流类比模型－Ｒｏｈｓｅｎｏｗ模型进行了修正．通过对实验数据的检验，表明修正后的模型预示值与实测结果吻合很好．

It is known that surfactant additive has important effect to nucleate boiling, surfactant additive mainly intensifies the convection of fluid while it changes the attribution of bubbles. Due to the extensive application of Rohsenow model as the convective heat transfer model, we revise the Rohsenow model to take consideration of the effect of wettability for surfactant additive. The experimental data reported in Ref. [1,8] show good accordance with the prediction of revised Rohsenow model, Eq.(9).
