i have two cylinders placed co axially. inner one is solid and small. the outer one contains fluid. the inner one is rotating with respect to its axis. can we simulate in flow simulation?
therefore SW cant simulate this problem?
You can simulate it in flow. You just need to apply wall condition to cylinder face. You need to choose Boundary Condition Type Wall and in Wall motion angular velocity.
It is possible because fluid geometry (mesh) remain stationary during calculation.
plz can you explain? i can do if you tell me step by step.
is this external or internal flow?
you should do the tutorials before you go asking for this kind of help in my humble opinion.
You should read help and tutorial files attached to flow works. To understand this task. Without it you will not be able to define (or even explain) problem and understand results.
I can't tel you if this is internal or external, it depends from many things.I think that this is internal, but there is a lot of Boundary Conditions depending on geometry.
