Abstract

Cavitation is a design consideration for a broad variety of devices handling liquids. Cavitation can affect performance, for example through increased drag of hydronautical vehicles, limitations on the thrust produced by various propulsion systems, decreased power output and efficiency of turbines, and a drop in head and efficiency produced by Noise and vibration occur in many applications, ranging from all forms the deleterious effects of performance breakdown, noise, and vibration, there is the possibility of erosion. Erosion can range in extent from a period of time. An extreme example is shown in Figure 1, which disastrous failure of large and expensive structures in a relatively short pumps. The accuracy of flow meters can be affected by cavitation. of turbomachinery to large valves in industrial plants. Associated with relatively minor amount of pitting after many years of operation to illustrates the damage sustained in the spillway tunnel of the Yellowtail Dam in South Central Montana. Numerous descriptions of cavitation damage are available in the literature (e.g. Vennard et al 1947).
