Key words: engines.

Results are given of the calculation evaluation of the water flow speed effect on the vapour bulb growing and condensation time. At the flow speed above 0.2 m/s the condensation time exceeds the bulb growing time, and the local speed of a water-vapour mixture will increase by 40 % and more, comparing with the flow core speed, and the increase of the local speed is quite significant within the range of the average flow speed from 0.25 to 0.55 m/s.
