Openfoam Vortex and Whirlpool simulation

qolt45 · October 3, 2013, 08:15

Hi guys,

I have a problem about whirlpool simulation in openfoam. Simply i made a cube and merge with cylinder in front. Then i tried to observe whirlpool around the cylinder inlet. But i don't know which model should i use to simulate or get nearby this whirlpool simulation.

I tried LES model but i couldn't see anything. Now i'm going to try RAS model. Also i'm solving my system by using interFoam.

Could anyone give me advice for this simulation ?

I have done simulations with LES model but results are not enough to see the whirlpool in simulation. Many of the models is used during the simulations. Also RAS model is used for calculations but results are not convinience to know vortex happened in that geometry.

But i will change the models for RAS to generate another simulations. Could anyone give me advice for this situation?
