Rotating Geometries

[dustinweaver]

Hi all,

I’m PhD student at University of British Columbia. My current research is using LB for mixing tanks. I don’t want to use commercial software for this because I want to develop something and contribute to the opensource community. I have been over the documentation on OpenLB and have only been able to find a very interesting journal article, “An extension of the Lattice-Boltzmann Method for simulating turbulent flows around rotating geometries of arbitrary shape”. Is there a tutorial on rotating geometries or even an example code?

Thank you 😀 ,
Dustin

Dear Dustin,

there a several approaches to realize a rotating geometries. In the paper it was realized by boundary conditions only. Here, https://www.youtube.com/watch?v=Msh2iyG6-ho we used a moving frame (basically you get a force term (there are funcztors in OpenLB to do that easily)). We have no example ready to give you. Maybe, it is a good idea to come to our next spring school which is soon to get started and in the last part we help you with your problem.

Best
Mathias

Hi Dustin and Mathias,
Could you realise a working case with rotating geometry meanwhile?

We had no capacities for it. In the framework of a common project we are happy to push it..
