Once you have the required flow rates, size the physical dimensions: Motive Nozzle Throat ( cap A sub 1 Function of motive steam flow rate, pressure ( cap P sub p ), and temperature. Ejector Throat ( cap A sub 3
: This is a widely used free spreadsheet on Cheresources based on semi-empirical equations for entrainment ratio. It uses curve-fitting constants for both choked and non-choked flow conditions. ejector design calculation xls
Suction Fluid (Air):
In the world of fluid dynamics and process engineering, the ejector (or eductor) is a deceptively simple device. With no moving parts, it uses a high-pressure motive fluid to entrain, compress, or pump a secondary low-pressure fluid. From vacuum distillation in oil refineries to chemical dosing in water treatment, ejectors are indispensable. Once you have the required flow rates, size
