Flow is controlled by either throttling or diverting it. Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

In this paper we describe the application of a CFD methodology to characterize the orifice flows over a wide range of flow conditions with various geometrical features commonly found in hydraulic ...

Complex entrance profiles boost orifice-flow efficiency but at the expense of repeatability. Changes in flow rate through a scuba oxygen analyzer can prove dangerous, even deadly to a diver. That's ...
