| Summary: | Ejectors are widely used as effective distributors inmanychemical and bioprocess industries. Gas entrainment
rate as a function of liquid flow rate in ejectors is investigated using nozzles of different geometries.
The data are analyzed through macro-energy balance for each phase considering air and water inlet line
discharge coefficients. Nozzles with smaller discharge coefficients are effective in producing higher vacuumand
hence higher entrainment rates. It has been observed that the factor limiting the air entrainment
rate is the low discharge coefficient in the air inlet line. Higher air inlet line discharge coefficients can
increase the entrainment rate. |
