hi
I just start to learn the Lattice Boltzmann Method and I work on couette flow.
I read some articles about this subject but i’m very confused and i can’t write numerically what i read.
Can anyone help me in this subject? or have a simple working example?
Please help me if you can.
Dear Timm
Thank you, it was very helpful
I have just a question, in my case the flow is between two cylinder and the inner cylinder is animated with an angular velocity
can you help me how to proceed?
thanks
Hello,
rotating cylinders are much more complicated in LBM. You have to use boundary conditions which are not mesh-conform. This can be done, for example, with the immersed boundary method or with interpolated bounce-back. Another option is a generalized boundary condition. You could have a look at this article: Verschaeve, J. Comput. Phys. 229 (2010)

Hello, I’m also interested about an example of the implementation of a Couette flow but your link seems not valid anymore.
Could you post it again please?
Many thanks in advance,
François
page not found!!! could you upload the code?
