The two-fluid model is a new method proposed recently to calculate the two-phase flow problem. In solving the governing equations of each phase, it also considers the momentum, energe and mass transmission between the two phases. The objective of this work is by using this model to calculate the vapour-liquid flow through a heated pipe. The result seems physically reasonable. This shows that the two-fluid model is a potiential way for analysing two-phase flow, but some of its assumptions have not yet been verified,...
