International workshop on two-phase flow fundamentals
Abstract
The objectives of this Workshop on two-phase flow and heat transfer phenomena were to reach agreement on future research. The results of an extensive Physical and Numerical Benchmark Exercise were presented at the Workshop held at Rensselaer Polytechnic Institute (RPI). It was shown that, while numerical methods exist with which to evaluate both one-dimensional and multidimensional two-phase flows, current analytical models are often inadequate. In particular, it was demonstrated that no preferred general closure laws exist for two-fluid models of two-phase flow. Several lectures summarized the state-of-the-art in two fluid modeling, numerical methods and two-phase instrumentation and experimental techniques. These talks stressed that there is uncertainty in the ability to model interfacial transfers and that the instrumentation needed for the measurement of many key parameters often does not exist. In anticipation of the need to further assess two fluid models of two-phase flow various new benchmark data sets were discussed and selected. Significantly, some of these data sets highlight multidimensional aspects of two-phase flow, while in others nonequilibrium phenomena are significant. The Workshop was evaluated by a distinguished panel that comprised an Evaluation Committee. Their report is given in this report.
