摘要：

The present study aims to investigate turbulent film condensation on an inclined tube with variable wall temperature. The analysis proceeds under the effects of liquid-vapour interfacial shear and eddy diffusivity. In order to forecast the results more exactly, a new theory model of local film shear stress (tau/tau w) is presented in the paper. The numerical calculation is obtained by using Visual C++. Net. The results show that the increase in the temperature amplitude will bring about a larger Nusselt number under high velocity vapour. Besides, the results present the optimal inclination angle of the tube in different wall temperature amplitudes.
