The study of aerodynamic flow control and base pressure analysis is central to advancing the efficiency and performance of high-speed vehicles and industrial processes. By manipulating the flow field ...

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, ...

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 ...

Flow Meters and Controllers measure and control the flow of gases, liquids, steams, or slurries into a chemical process. These devices address flow rate in units of mass, or units per length of time, ...

In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

Turndown ratio can be defined as a measure of the usable range of an instrument. It is expressed as the full-scale range divided by the lowest point of measure. It indicates the instrument range ...
