This invesligation deals with the feasibility of quick cooling of hot surfaces by means of a water jet. The temperatures of the hot surfaces arc above boiling in the region of partial nucleate boiling with an unstable film. Experiments were performed in which a heated pipe was sprayed with a water j

โฆ Synopsis
The presence of reflecting boundaries causes the acoustic power output of a point source to increase. As existing experimental data were found to be inadequate, experiments have been carried out in this study to determine the effect of a reflecting plane on the power radiated by a point source. A corona-type monopole was used in this study. Both source and receiver positions are varied," the statistical results of power radiated are compared with the theoretical predictions.
