2020-9-3 · The impact of nozzle hole inlet rounding on nozzle performance is illustrated in Figure 16 where the effect of different nozzle hole inlet chamfer radius (r c) is simulated [2208]. In this example, the baseline case with no rounding of the nozzle inlet shows a C d of about 0.75 at low pressure (i.e., low flow rate) and about 0.64 at 100 MPa.

Get Price2020-8-17 · Jet pumps are centrifugal pumps with an ejector (venturi nozzle) attached at the discharge outlet. They function based upon the Venturi effect of Bernoulli's principle - utilizing constriction to reduce pressure and provide suction. After the pump is primed, a motive fluid is pumped through a standard centrifugal pump and enters an ejector.
