Study on Optimization of Flow Control Using Different CFD Approaches – A Review

Abstract

Optimization techniques are commonly used as fluid flow control equipment’s in many engineering applications. Thus it’s more and more essential to know the flow characteristic inside the valve. Due to the fast progress of the flow simulation and numerical technique, it becomes possible to observe the flows inside a valve and to estimate the performance of a valve. This review presents the modeling and simulation of the flow components. The flow system with globe valves is complex structure and has non-linear characteristics, because the construction and the hydraulic phenomena are associated of globe valves. In this paper, three-dimensional CFD simulations were conducted to observe the flow patterns and to measure valve flow coefficient when flow component valve with different flow rate and constant pressure drop across the valve were used in a valve system. Furthermore, the results of the three-dimensional analysis can be used in the design of low noise and high efficiency valve for industry.
