There is a lot of an emperical component to vacuum jet design and manufacturing. Calculation for the ejector design using the correlations is also developed. Full-Text Paper (PDF): Empirical correlation for ejector design. To validate the CFD simulation, the numerical predictions. (CFD) software, was used to model gas ejectors.
Gas Ejector Modeling for Design and Analysis. Results compare favourably with actual ejector installations, see graph to the left.Steam Jet Ejectors)' IPS-E-PR-750 'Process Design of Compressors' IPS-E-PR-755 'Process Design of Fans and Blowers' This Standard covers: VACUUM EQUIPMENT (VACUUM PUMPS AND STEAM JET EJECTORS) This Standard covers the process aspects of engineering calculations for vacuum systems and the relevant equipment. The model has been tested extensively and is easy to use. The ratio of entrained gas flow rate to motive gas flow rate (entrainment mass ratio) Motive gas flow rate, pressure, temperature and properties (molecular weight, Cp/Cv)Įntrained gas properties (molecular weight, Cp/Cv), pressure and temperature 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." "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
