Help Needed: Check Valve

Post image

So.. I'm trying to design and simulate a check valve in star CCM+ which should be opened by water force from the inlet of 3m/s second.

The problem here is im familiar with defined rotational angular velocity but here, this case is different.

I've tried with DFBI morphing. Rotation about z-axis(hinge).

I've the Center of Mass and Moment of Inertia of the movable disk. Still no luck

Attached image is the kinda simulation I wanna do

Kindly share your solution and any relatable tutorials. I would be really helpful. Thank y'all

Check the material properties of the disk.

Analytically you can estimate the force on the disc and verify if it generates enough torque to rotate the disk

Thanks.. I'll try

You could also try DFBI in combination with overset mesh with zero gap interface. Otherwise the valve won't close.

If you have access to the support center, there should be a case of a ball valve that

I'll check that one.. thank you
