Dynamic Mesh: Check Valve

Master Check Valve CFD Simulation with Dynamic Mesh in ANSYS Fluent

Step into the world of advanced fluid dynamics with this comprehensive episode on Check Valve CFD Simulation using the Dynamic Mesh capabilities of ANSYS Fluent. This hands-on tutorial forms the third chapter of our Dynamic Mesh Training Course and is designed to raise your simulation skills to a professional level.

In this practical session, you will learn to simulate the intricate flow behavior of a check valve in ANSYS Fluent. The episode guides you through the entire workflow — from geometry creation to result analysis — with a particular focus on the dynamic mesh techniques that make this kind of simulation possible.

The episode begins with the fundamentals of check valve dynamics, covering the mechanics of unidirectional flow, the opening and closing behavior of the valve, and the coupled interaction between the fluid flow and the valve's motion. From there, it moves into model setup and meshing, where you will create the geometry in Design Modeler, apply meshing techniques in ANSYS Meshing, and build an understanding of the computational domain — a pipe fitted with a check valve.

With the model in place, the focus shifts to the dynamic mesh implementation itself. Here you will learn to apply the Six Degrees of Freedom (6-DOF) solver, define the rotational motion of the valve, and set up deforming mesh zones that adapt as the valve moves. The episode then explores several advanced techniques to enrich the simulation, including setting up multiphase flow with the Volume of Fluid (VOF) model, capturing time-dependent flow behavior, and using Execute Commands to control the inflow conditions.

The methodology follows a clear, step-by-step approach so that every aspect of the simulation is understood: configuring the dynamic mesh model for valve motion, defining rigid body motion for the valve, implementing multiphase flow for water and air, and selecting appropriate solver settings for transient analysis. In the results and analysis stage, you will learn to interpret and visualize the outcomes — analyzing the water mass fraction contours, creating animations of the valve movement and flow behavior, and verifying that the check valve mechanism operates correctly.
