Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

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 order to understand the benefits and drawbacks of the melt-flow-rate (MFR) test completely, it is essential to know something about how the test is carried out. The methodology is included in ASTM ...
