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 ...

These graphs compare the pressure/flow characteristics of orifice and capillary restrictors. The characteristic impedance of an orifice restrictor does not vary linearly, so it will not always match ...

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 today’s environment technology is constantly pushing for improved system efficiencies and industrial hydraulic systems is a good example of this where reduced weight and size of components and ...
