抄録

The influence of water temperature on cavitation erosion has been studied using a vibratory apparatus, but no researches has been conducted at a constant cavitation number in flow condition.This study deals with the influence of water temperature on cavitation erosion using a cavitating liquid jet apparatus. The optimum stand-off distance at 25°C was 11, 15, 21 and 25 mm at cavitation number of σ=0.03, 0.025, 0.02 and 0.015, respectively, and was almost the same as that of a guideline in ASTM G 134 standard. The optimum stand-off distance at 75°C is similar to that at 25°C. The erosion rate increases with liquid temperatures and reaches a peak, followed by a decrease. The peak appears at the approximate average of freezing and boiling temperatures. The relative temperature was defined as 0°C for breezing temperature and 100°C for boiling temperature under the pressurized water. The erosion rate increases at 1%/°C between 5 and 45°C of relative temperatures, and decreases at 2%/°C between 45 and 80°C.
