“…Eames [2], for example, proposed a new formulation of the equation of momentum applied to the modeling of a supersonic jet ejector pump. Eames [3] also conducted an experimental and analytical study of a steam ejector refrigeration machine. Fan et al [4] proposed a compressible fluid CFD model of a jet in an ejector pump.…”

Abstract:The purpose of this study is the dimensioning of the cylindrical mixing chamber of a compressible fluid ejector used in particular in sugar refineries for degraded vapor re-compression at the calandria exit, during the evaporation phase. The method used, known as the "integral" or "thermodynamic model", is based on the model of the one-dimensional isentropic flow of perfect gases with the addition of a model of losses. Characteristic curves and envelope curves are plotted. The latter are an interesting tool from which the characteristic dimensions of the ejector can be rapidly obtained for preliminary dimensioning (for an initial contact with a customer for example). These ejectors, which were specifically designed for the process rather than selected from a catalog of standard devices, will promote energy saving.

“…Using water as refrigerant in a steam jet refrigeration cycle has some drawbacks. The cooling temperature is limited to above , 1995;Aphornratana and Eames, 1997] have shown that a steam jet refrigeration cycle requires the vapour-generator saturation temperature between 120°C to 140°C. The system also needs to be operated at a relatively low condensing temperature.…”

In this study CFD technique was employed to investigate the effect of divergent angle of primary nozzle, NXP (NXP = Distance between the nozzle exit to mixing chamber inlet) and throat of the ejector on the performance of ejector using the steam jet refrigeration cycle. In all these cases, only one fixed mixing chamber with different divergent primary nozzle, NXP and throat of an ejector was investigated numerically using the commercial CFD package, the effect of primary fluid pressure mass flow rate and mach numbers were observed and analyzed. The velocity contour lines were used to explain the happening of process inside the ejector it was found that the throat diameter, NXP and diverging angle of primary nozzle plays a crucial role in the steam jet refrigeration.
