Research of Flow Coefficient of New Throttling/Sealing Valve Based on CFD

Abstract:

The flow coefficient of the valve is an important index of measuring the valve circulation ability, a major process parameter of and a significant technical indicator of valves and regulating valves on an industrial basis. Numerical simulation was performed on the flow coefficient of the valve by using FLUENT, software of computational fluid mechanics and by the standard model. The flow and the resistance coeffients were obtained based on the numerical simulation of a new type of throttling /sealing valve under the same pressure differentials but with different opening conditions. The results demonstrate that the flow coefficient of the throttling/sealing valve is in close compliance with the typical curve of equal percent, and thus provides an important basis for its optimized control.
