Influence of air content in water on cavitation region in mathematical model

Abstract

The air content in the water is parameter, which plays a big role in formation of cavitation region. This value is not measured in physical experiments. Mathematical models of cavitation take the air content into account. The zero value causes even non- convergent solution. In this paper the air content values in Singhal cavitation model are tested and the influence on the size of cavitation region is evaluated. The results are compard with physical experiment, defined by the water flow through Laval nozzle.
