Abstract

The aim of the article is improvement of numerical cavitation models for simulation of an effect of cavitation stabilization of fluid mass flow. The methods of development of a new dynamic component for a numerical model of cavitation mass transfer is presented in the paper. Application of the new method resulted in a new dynamic component for numerical model of cavitation mass transfer, which takes into account fluid viscosity in Reley-Plesset equation. Relying on the methods being considered fundamentally new hydroautomatic devices such as cavitation mass flow stabilizers and flow dividers could be designed. The new dynamic component has become the basis for the new numerical model of cavitation mass transfer. The effect of cavitation stabilization of fluid mass flow was simulated by this dynamic component. The numerical model was verified by experimental researches of the effect of cavitation stabilization of fluid mass flow in a jet element “pipe-pipe”. The results of simulation showed that the new numerical model of cavitation mass transfer can simulate the jet pipes with the difference between results of simulation and experiment not exceeding 2,5% and visualizing a cavitation zone more adequate.
