Gas Ejector Design Calculation Xls _verified_ Site

Use Excel’s Solver to optimize nozzle/throat ratio for maximum entrainment.

The XLS automatically suggests nozzle diameters and checks for over-expansion or under-expansion.

Note: If ω is unknown, the XLS will solve for it based on operating limits. gas ejector design calculation xls

While Excel is great for preliminary sizing, it often fails to account for: If liquids drop out during expansion. Complex Geometries: Non-standard nozzle shapes.

For a choked motive nozzle, the throat area ( Atcap A sub t ) is determined by: Use Excel’s Solver to optimize nozzle/throat ratio for

Pressure and temperature of the driving fluid.
