Abstract
The calculation procedure of the ejector with water-vapor condensation in primary nozzle and in converging chamber is presented. Calculations are performed in a wide range of temperatures of primary and secondary gases. The differences are identified in the properties of gas- and vapor-driven ejectors. Limiting mass rates ratios of gas ejectors are reached by primary temperature increase, but the highest performance of vapor-driven ejectors is realized with the use of saturated vapor.
