The limited data that do exist from Ruch and Holman [ 17 ] indicated no significant effect on heat transfer with phase change due to the angle of the jet...

..., the rate of hole opening is rapid, with the major portion of the holes opened within 25 ns. The second stage of the process is slower and lasts between 100 and 200 ns. The rapid hole opening process at high fluences can be attributed to recoil pressure from explosive phase change. Measurements...
