Sekundarni naslov: | Numerical simulation of cavitating flow through radial divergent section |
Sekundarni povzetek: | Cavitation is a phenomenon of liquid transition to the vapor and back to liquid. It occurs at sudden drop in pressure. The positive effects of cavitation are commonly used in medicine while its negative effects impact on the operations of turbine and other machinery. Probable the most common negative effect of cavitation is the cavitation erosion caused by the implosion of vapor bubbles near a solid surface. The thesis discusses about the accuracy of three different mass transfer models for prediction of cavitation which were tested numerically using ANSYS CFX simulation program. They were tested on the model of divergent radial test section. The results of numerical simulations were compared with the results of experimental measurements performed at the University of Grenoble. In the thesis we performed out steady simulations using all three mass transfer models. We also performed out transient simulation using Zwart model. Based on the presented results we concluded that all mass transfer models correctly predict the area of cavitation formation. |
