Abstract

The process of rarefaction wave propagation upon sudden contact of cold water and saturated vapor is studied. It is shown that the most intensive steam condensation occurs over a time interval of about 0.01 ms, during which the water surface heats up. Then a constant temperature difference of 2-3 degrees is formed between the water surface and the steam and thus the condensation intensity is reduced.
