Three-Dimensional Simulation of Two-Phase Flow in Pipes

摘要

A two-phase flow of water in a pipe is investigated experimentally and numerically. A three dimensional simulation is performed using an. enhanced two-fluid model. To take phenomena like phase change and a possible change of the flow regime into account, adequate inter-phase exchange terms were implemented. The results show that three dimensional phenomena in pipe elements can have a significant influence on the integral parameters of the flow situation.
