Abstract
De Laval type nozzle was designed for expanding the vapor with pressure ratio of about 7: 1 and at the following compress parameters: the maximum pressure of 70 bar, the maximum temperature of 320oC. The nozzle had a rectangular cross section. Placed in the movable element ensures unifconstant orm rate of expansion: P=-(1/p)(dp/dt) equal 104 s-1 in place of supersonic flow (condensation). A stationary probe for measuring the static pressure was placed in the upper wall of the nozzle. Boro-silica window glass contained in the walls allow observation of the flow at this location.
