Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Beyond the wheel, the most important mechanical equipment serving humanity is the centrifugal pump. Centrifugal pumps make modern quality of life possible. Turn on a faucet and a centrifugal turbine ...

Integrated slug-flow optimization can mitigate flow problems in a wide range of both offshore and onshore operating conditions. Slug flow is one of the most common flow states in horizontal and ...

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, ...
