Secondly, the flow of condensation steam was compared with the flow of ideal gas. From the contrasted results, it can be found the difference between the condensative steam flowing and ideal-gas flowing. And, it also can be found out that it is inevitable to condense for steam flowing under the supersonic state. At the same time, the major areas which formed second drips have been displayed in the solved results. Finally, the flow of condensation steam in the 3-dimension model has been simulated.
