Commercial CFD software research and internal flow check valves

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  2 way manifolds  an important 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, commercial CFD software research and internal flow check valve, mainly to do the following tasks: outlines the current situation and the check valve design  Valve manifold  fluid  Instrumentation ball valve  the check valve in the common software applications. Details of the basic theory and computational fluid dynamics method, the calculation method for solving algebraic equations and a variety of mesh generation techniques. Finally, multi-channel Ball Check Valve internal three-dimensional incompressible turbulent flow was simulated, and the results are experimental verification.
