Note (General): 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℃ was ll, 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℃ is similar to that at 25℃. 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 emperature was defined as 0℃ for breezing temperature and 100℃ for boiling temperature under the pressurized water. The erosion rate increases at 1%/℃ between 5 and 45℃ of relative temperatures, and decreases at 2%/℃ between 45 and 80℃.
