Hello to all,
I am actually working with a square block in a square channel with a poiseuille flow (D2Q9), I am able to evaluate the drag and lift of the fixed obstacle with Momentum exchange Method and i am using the half way bounceback, so I don’t get function distribution values from the wall nodes.
But now I would like to implement a particle movement model to this obstacle, so it would move along with the flow drag…
I do not know ANYTHING more that the newton’s motion laws. How do you recommend me to start with? My main questions are:
[b]if i change the particle to a circular particle, should I change something on my MEM and bounceback at first sight?
where do I have to implement my new routine for image update due to the particle movement, before or after the streaming step?
Where I can find some good info about detailed particle models for LBM?[/b]
Thanks in advance, and I wish all of you a nice Christmas vacations!!!
