Flow past rotating cylinder

sam.ho · October 10, 2013, 02:15

HI Foamers

I want to set up a case of Flow past a rotating cylinder. And have some basic questions which i am not aware of...

1. Is it possible to give rotation condition to cylinder instead of stationary ? If yes How to do it ?

2. Which solver helps to solve this problem ?

Please give more info about a case set up of rotating bodies in OpenFOAM ...

Dear Sam.ho

You need to detail your case more in order to get some help

Hi,

Please find the attached picture which explains my problem.
And i am reading the research paper to arrive at geometric dimensions, Boundary conditions and meshing.
I just want to know
Which solver can be used for this problem ? and how to give rotation to Cylinder during simulation ?

Hi,

you can use either MRFSimpleFoam or pimpleDyMFoam. Take a look at the tutorials which are using these two solvers (especially the one with the title: mixerVessel2D)

hope it helps.
