The ratio of the mixing chamber diameter to the nozzle diameter typically ranges between for optimal performance. Nozzle Position ( cap L sub g a p end-sub
A standard design spreadsheet typically includes the following core components: Entrainment Ratio ( ejector design calculation xls
To use the spreadsheet, simply fill in the yellow cells in the tab:
This Excel sheet is built upon the and the Conservation of Energy and Mass . Ejector Design Calculation xls: A Comprehensive Guide to
To construct your spreadsheet cells, apply this structured reference layout for your formulas: Excel Formula Template Engineering Description =SQRT(Gamma * (8314 / MW) * Temp) Speed of sound in the fluid medium. Nozzle Throat Area mm2m m squared =(MotiveFlow / (3600 * ThroatDensity * SonicVel)) * 10^6 Minimum cross-sectional area of nozzle. Expansion Ratio =MotivePressure / SuctionPressure Pressure drop driving force across nozzle. Entrainment Ratio =VLOOKUP(ExpansionRatio, HEI_Table, 2, TRUE) Suction capacity per unit of motive fluid. 5. Troubleshooting & Validation Tips
Developing an allows engineers to transition from relying on manufacturer catalogs to designing custom, optimized solutions. By blending 1D thermodynamic equations with empirical correlations in Excel, you can accurately predict ejector geometry and performance, ensuring high efficiency for your specific application. Nozzle Throat Area mm2m m squared =(MotiveFlow /
Optimize the mixing tube diameter for different suction flows. Compare various efficiency scenarios efficiently. 5. Validating Your XLS Tool
Calculating the expansion angle to decelerate the fluid and maximize pressure recovery. 3. Creating an Ejector Design Calculation XLS Tool
To build a robust calculation spreadsheet, you must program the governing thermodynamic equations for compressible gas flow. The expansion through the motive nozzle is modeled using isentropic expansion relationships. Motive Nozzle Velocity The theoretical velocity (
