CFD Simulation of Ejector in Steam Jet Refrigeration

Abstract

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.

Thermal and anticorrosion properties of polyurethane coatings derived from recycled polyethylene terephthalate and palm olein-based polyols

“…This appears possibly that some soft-hard segment phase fraternization could occur in the system interrupting the crystallization of the soft segment. The presence of the amorphous and crystalline phases in the XRD diffractographs present in a real polymer, signified that polyurethane is a good polymer for industrial applications [33].…”
