Thermodynamic models, Continuity equationsĮfficiencies of each step within the ejector based on correlations T he ejector computer model includes the following: 'I was able to prepare a very successful solution!ĮZEJECTOR is a computer model for gas ejector and steam ejector design that has been developed based on a unique approach using fundamental principles. 'According to program steam flow and sizing seems perfect!' 'Your software is very well designed and easy to use with plenty of great info.' This device uses water vapor as the working fluid and operates at 7.5 bar motive pressure, 63☌ and 80☌ for suction and discharge temperatures, respectively.'Before including a compressor or pump in your process design, would you fill in your request, send it to a supplier and then cool you heels waiting for a reply? So don't do this for an ejector.'Īvoid the time lost, develop your own solution The results indicate that these variables can affect both the entrainment ratio and critical back pressure. Finally, the effect of various nozzle exit plane diameters which cause different Mach numbers at the nozzle exit is investigated on the thermocompressor performance. Then its performance is analyzed by choosing different operating conditions at the boundaries and also different area ratios which is one of the significant geometrical factors to describe the thermocompressor performance. Since the flow is turbulent and supersonic, CFD is an efficient tool to reveal the phenomena and mixing process at different part of the thermocompressor which are not simply obtained through an experimental work. This paper first describes the flow behavior within a designed model of a thermocompressor using the computational fluid dynamics code, FLUENT.

The performance of a thermocompressor highly depends on its geometry and operating conditions. They work like a vacuum pump but without usage of any moving part and so they can save energy.

They are devices that use the energy of a high pressure fluid to move a low pressure fluid and enable it to be compressed to a higher pressure according to the principle of energy conversion. Thermocompressors are widely used in a large number of industries that use steam as their heating medium or as a power generating utility.
