摘要：

Based on cavitation modelling in Laval nozzle results and experience, following problem was defined. Flowing of water on turbine blade wheel outlet is the main point of the problem. Nowadays there is a chance to model the cavitation in Fluent system, where solution of two-phase mixtures (water-liquid and water-vapour) and more accurate three-phase mixtures (water-liquid, water-vapour and non-condensable air) are presented. It is possible to use "Full cavitation model" or "Schnerr and Sauer model" (simpler model) or "Zwart-Gerber-Belamri" for modelling this phenomenon. All the models take under account dynamics of vapour bubbles. All the models are compared in this article. (C) 2011 Published by Elsevier Ltd.
