Three-Dimensional Analysis of Partially Open Butterfly Valve Flows

Abstract

A numerical simulation of butterfly valve flows is a useful technique to investigate the physical phenomena of the flow field. A three-dimensional numerical analysis was carried out on incompressible fluid flows in a butterfly valve by using FLUENT, which solves difference equations. Characteristics of the butterfly valve flows at different valve disk angles with a uniform incoming velocity were investigated. Comparisons of FLUENT results with other results, i.e., experimental results, were made to determine the accuracy of the employed method. Results of the three-dimensional analysis may be useful in the valve design.

Experimental and numerical study of a choke valve in a turbulent flow

“…12, is similar to one observed in the article [8] that used the k ε -turbulence model. The flow deattaches on the other tip of the butterfly valve, and makes a turn to pipe centerline.…”

“…The study solved the time averaged velocity profile after the valve, but did not discuss the threedimensional structure of the flow. A later study [8] used Fluent software to compute three dimensional incompressible flow past the butterfly valve with low Reynolds number (the bulk Reynolds number was around 25,000) using the k ε -turbulence model. A typical problem associated to LDV measurements in calibration use is the determination of the mean volume flow rate.…”

Performance test and flow visualization of ball valve

“…Davis and Stewart [9] adopted FLUENT TM to study flows in global control valves. For three-dimensional analysis, Huang and Kim [10] utilized FLUENT TM to simulate turbulent flows in a butterfly valve. The k-e model was employed in their numerical simulation.…”

Multidisciplinary optimization of a butterfly valve

“…The first paper researches the torque characteristics, and the second focuses on the pressure drop induced by the valve disc. In 1996, Huang and Kim [2] investigated three-dimensional analysis of partially open butterfly valve flows by using commercial code FLUENT, the characteristics of the butterfly valves flows at different valve disc angles with a uniform incoming velocity were investigated. Park and Chung [3] gave a theoretical study on hydrodynamic torque of the butterfly valve through the free streamline theory with a newly devised iterative scheme.…”
