Description

The paper presents the analysis of the possibilities of using Computational Fluid Dynamics technology for calculating of the flow parameters in a cavitation tunnel. Different turbulence models are used to perform the calculations. Comparison of the results from the experimental work and the CFD-TASC flow analysis are presented. Cavitation is addressed as a particular phenomenon, but also its influence on the hydrodynamic parameters. Constant enthalpy vaporization model is used for this purpose and the results will be compared with the photos taken during the cavitation investigation in the tunnel. (Original)
