Boiling curves for water cooling of high temperature materials were obtained. Surface temperature and heat flux were calculated from measured temperatures in the test material (copper) by means of extrapolation based on the finited difference equation of heat conduction. Boiling curves were obtained in following cases:
1. low pressure water jet cooling,
2. high pressure water jet cooling,
3. water spray cooling.
Effects of water flow rate, water temperature and water pressure were studied. Cooling processes for ultrasonic inspection and water quench of steels plates were calculated from the boiling curves and compared with the measured results. Errors due to the measuring method of boilingcurve were studied.
