How does a venturi injector work?

Fluid with a certain pressure passes through the nozzle, converts hydrostatic energy into kinetic energy, forms a certain negative pressure, and at the same time transfers kinetic energy to the second fluid to achieve the purpose of sucking the second fluid. The two fluids are mixed in the ejector, and the mixed liquid is discharged after passing through the diffuser tube. The diffuser tube can reduce the flow rate of the mixed liquid and increase the static pressure to reduce losses.

In this process, the requirements for fluid transportation and mass transfer are achieved.

The structure of the jet is generally: nozzle, suction chamber, throat, diffuser tube.
