摘要

In this experimental investigation of condensation heat transfer, the effects of film Reynolds number Re_F, Prandtl number Pr_F and interfacial shear stress τ_v have been studied independently. For condensation without considerable interfacial shear stress τ_v , correlations from the literature are confirmed. In the case of increasing values of τ_v a re- duction in heat transfer coefficients is found Re_F < 10 and an increase for 20
