A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

The paper proposes the full linearization of nonlinear characteristics of flow control valves via variable gear ratio design. The inherent nonlinear function of the normalized valve capacity ...

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 ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

This paper systematically elaborates on the turbulence model, multiphase-flow model, and noise model. The turbulence model is adept at accurately characterizing the flow behavior of complex fluids. In ...
