Discharge and diffuser

It is defined as: ER = Mass flow of entrained (suction) fluid / Mass flow of motive fluid

PmPs≥(γ+12)γγ−1the fraction with numerator cap P sub m and denominator cap P sub s end-fraction is greater than or equal to open paren the fraction with numerator gamma plus 1 and denominator 2 end-fraction close paren raised to the the fraction with numerator gamma and denominator gamma minus 1 end-fraction power

If you design multiple ejectors for different clients, log each design in a database sheet and analyze trends (e.g., which CR range gives highest efficiency). ejector design calculation xls

Before diving into the calculations, let's review the basic components of an ejector:

w=A×ErB×PcC×PpD×e[G+H×ln(Pc)]w equals cap A cross cap E r to the cap B-th power cross cap P sub c to the cap C-th power cross cap P sub p to the cap D-th power cross e raised to the open bracket cap G plus cap H cross l n open paren cap P sub c close paren close bracket power

Incorporate a simple lookup table or VBA macro for steam properties (IF97 steam tables) if using steam as the motive fluid. Calculate density, sonic velocity ( ), and specific enthalpy for all states. Tab 3: Sizing and Geometry Calculations Discharge and diffuser It is defined as: ER
