The design check valve status and computational fluid dynamics of common software applications in non-return valve

From the study of fluid flow valve mechanism departure, using numerical simulation valve internal flow, numerical simulation results to guide the design of the valve has gradually  Stainless steel needle valve  research direction. Numerical simulation tools, one can save test resources, shorten new product development time; hand it can display is difficult to draw from the test flow characteristics in detail. In this paper,  Valve manifold  FLUENT study the internal flow check valve, mainly to do the following aspects: the design brief check valve status and computational fluid dynamics in the check valve in the common software applications. Details of the basic theory and computational fluid dynamics methods for solving algebraic equations SIMPLE calculation methods and a variety of mesh generation techniques.
