CAVITATION DAMAGE AT ELEVATED TEMPERATURE AND PRESSURE

A discussion is made of the general effects of temperature upon cavitation damage rate at higher temperatures and pressures, with the maximum damage temperature increasing somewhat with the increased NPSH. Increased NPSH causes a strong increase of damage in this type of facility up to at least 4 atm NPSH. Obviously, damage must maximize at some higher NPSH and then decrease to near zero, since the number and size of bubbles decreases with increasing NPSH (though their collapse violence increases), reaching zero at sufficiently high NPSH, depending up facility frequency and amplitude.
