Ejector Design Calculation using Excel

1. Plant Engineers: Troubleshooting vacuum system issues or steam jet ejector performance in refineries and chemical plants.
2. HVAC Engineers: Designing ejector-based refrigeration or heat recovery systems.
3. Process Designers: Performing feasibility studies for gas compression without moving parts.
4. Students: Learning the principles of compressible flow and

A standard design spreadsheet typically includes the following core components: Entrainment Ratio (

Tip: When building your own XLS, always use absolute pressures for ratios, include steam/air table lookups via VLOOKUP, and add a Goal Seek macro to iterate for target entrainment ratio. ejector design calculation xls

Entrainment Ratio (Er)

The core performance parameter is the :

1. Objective

Ejector design calculations can be effectively performed using Excel. By creating a comprehensive template that includes input parameters, thermodynamic calculations, ejector performance calculations, and ejector geometry calculations, engineers can quickly and accurately design ejectors for various industrial applications. The sample calculations provided demonstrate the use of Excel for ejector design calculations. Ejector Design Calculation using Excel

• Use published performance curves from ejector manufacturers (e.g., Graham, Schutte & Koerting).
• Add 15-20% safety margin in motive flow.
• For critical service (vacuum towers, nuclear), use CFD or certified software.
