): Typically . Accounts for pressure recovery losses in the expanding cone.

: The resulting vacuum draws in a secondary "suction" fluid. In the mixing chamber, momentum is exchanged between the high-velocity motive stream and the lower-velocity suction stream.

: A high-pressure motive fluid (typically steam or gas) enters a converging-diverging nozzle, where it expands to supersonic velocities, creating a low-pressure zone at the nozzle exit. ejector design calculation xls fixed

The most critical dimensionless number in ejector design is the Area Ratio ($AR$). $$ AR = \frac\textArea of Mixing Throat\textArea of Nozzle Exit $$ This ratio dictates the operating curve of the ejector.

. Since the geometry is fixed, the ejector will only operate efficiently at its "design point." Off-Design Warning: "Note: Significant deviations in Motive Pressure ( cap P sub m ): Typically

) and physical dimensions (nozzle throat, diffuser throat diameter). 4. Troubleshooting and Optimization (Fixed Constraints)

Critical for "fixed" designs to ensure the combined flow reaches the required discharge pressure. 3. Performance Curves (Static Text) Include a section for Performance Mapping In the mixing chamber, momentum is exchanged between
