EXAMINATION OF THE TWO-PHASE FLOW MODEL IN VARIOUS FLOW CONFIGURATIONS

ABSTRACT
An integrated two-phase flow model including phase interaction is used to examine five particular systems of gas particles flows. The computations have been performed with the CFD software TASCflow3D of AEA Technology. The numerical results of TASCflow3DFLOW have been compared with experimental data and some of them with results from the second code in the project FASTEST of INVENT Computing from Erlangen. There are, of course, still some general problems to be solved for improving calculation efficiency of two-phase flow and to make the numerical codes more efficient in order to allow the calculation of more complex flow in experimentally non-established situation with an acceptable confidence. However, the problems become considerable smaller if consideration is based on proved elementary situations. In general, presented calculation results of test cases showed a quite good agreement with the experimental data. This gives significant contribution to overcome existing uncertainties in two-phase flow prediction. The results for these cases confirmed that the models work properly and that the two software packages in the project produce very similar results.
