Comparison of Different Mathematical Models of Cavitation
Cavitation occurs during the flow when local pressure drops to the saturation pressure according to the temperature of the flow. It includes both evaporation and condensation of the vapor bubbles, which occur alternately with high frequency. Cavitation can be very dangerous, especially for pumps,...

| description | Cavitation occurs during the flow when local pressure drops to the saturation pressure
according to the temperature of the flow. It includes both evaporation and condensation of the vapor
bubbles, which occur alternately with high frequency. Cavitation can be very dangerous, especially
for pumps, because it leads to break of flow continuity, noise, vibration, erosion of blades and change
in pump’s characteristics. Therefore it is very important for pump designers and users to avoid
working in cavitation conditions. Simulation of flow can be very useful in that and can indicate if
there is risk of cavitating flow occurrence. As this is a multiphase flow and quite complicated
phenomena, there are a few mathematical models describing it. The aim of this paper is to make a
short review of them and describe their approach to model cavitation. It is desirable to know
differences between them to model this phenomenon properly. |
