WebApr 1, 2024 · In the third zone, the entrainment ratio is negative (the entrained flow is reversed). 5.2 Influence of the Condensation Pressure on the Performance of the Ejector. ... (2024) Design of steam ejector in a refrigeration application based on thermodynamic performance analysis. Sustain Energy Technol Assess 31:369–382. Google Scholar WebThe effect of generator pressure was also studied. It was found that the entrainment ratio showed a maximum for constant condenser conditions. A near optimal condition of 70 kPa generator and 3 kPa condenser pressures were identified and tested in a preliminary experiment carried out with the solar driven ejector system installed in Tunis.
