For analysis behavior of the flow, we will use the following parameters: speed [m/s], direction (line of flow), pressure [MPa], turbulent kinetic energy, [[m.sup.2]/[s.sup.2]] volume fraction of pair phase [%], cavitation erosion
The part had an initial cycle of 5 minutes then inspected for any cavitation erosion
Cavitation in hydraulic machinery leads to the problems such as cavitation erosion
, vibration, pressure pulsation, and noise .
Besides, due to the continuously impingement effect of the burst cavitation bubbles, cavitation erosion
would develop on the blade surfaces.
The bursting bubbles in this manner would lead to the long run to corrosion of the valve surface over the long run further amplifying cavitation and cavitation erosion
Mechanisms of cavitation erosion
and characteristics of cavitation pits produced have been studied extensively [5-8].
The first observation of cavitation erosion
has been reported by Thorneycroft and Barnaby  much earlier than any data on sonochemistry or sonoluminescence.
The 20 papers here, about half of the presentations, discuss such topics as the formation and occurrence of non-metallic inclusions of silicon-doped steel during continuous casting, effects of carbon migration on sulfide stress corrosion cracking behavior of dissimilar joints in a wet hydrogen sulfide environment, the gas tungsten arc cladding of titanium-nickel overlays onto the carbon steel and stainless steel for cavitation erosion
resistance, the electromagnetic characteristics of iron-based microwave absorbing materials, and surface-texturing single-crystalline silicon wafers.
