Modeling leakage through surface asperities
All,
I hope you are doing well. I was wondering if someone had ever simulated flow through surface asperities (gaps) that are a result of surface roughness. I know that these asperities are usually on the micro-level. I am doing a project regarding leakage though metal-to-metal gaskets in API flanges to determine the leak rate in different surface properties. Would like to start a discussion if anyone has previous experience with this type of simulations. I am indifferent to using either ANSYS Fluent 17 or Star CCM+ 11 Best regards, |

Good luck. |
I was thinking more like generating a random 3D surface and attaching those node locations to the CAD model. Porous media would not take into account the surface roughness but that is a good way of modelling dynamic contacts.
