Abstract
The invention relates to the field of jet technology. After the required pressure of the gaseous medium at the gas inlet of a liquid-gas jet apparatus is obtained, the ratio of the liquid pressure in the nozzle of the jet apparatus to the pressure at the outlet of the jet apparatus is reduced in magnitude. Such ratio is reduced in magnitude down to the value at which an abrupt increase of gas pressure occurs at the gas inlet of the jet apparatus. This value of the ratio is fixed or determines the minimum value for such ratio. Then the final value of the ratio of the liquid pressure in the nozzle of the jet apparatus to the pressure at the outlet of the jet apparatus is set. The final value of the ratio must be greater than the fixed one. The process provides an increased efficiency for a liquid-gas jet apparatus.
