Greeting every one.
I have a case I want to work with in OpenFoam. The case is attached It imitates a fluidized bed. I have done a quarter of a cylinder to save on computational time. I have to issues I would want your help. 1. I want to patch the region between (0 0.1 0) and (0, 0.3 0) with solid particles of volume fraction 0.6 and this is the code I use in the setFields Dic defaultFieldValues ( volScalarFieldValue alpha.air 1 volScalarFieldValue alpha.particles 0 ); regions ( cylinderToCell { p1 (0 0.1 0); p2 ( 0 0.3 0); radius 0.055; //radius of the cylinder fieldValues ( volScalarFieldValue alpha.air 0.4 volScalarFieldValue alpha.particles 0.6 ); } ); Is this the right way to patch (ie. Using cylinderToCell command)? 2. I also do not want the particles to move to the region below (0 0.1 0); How do I go about this? Ie limiting the solid volume fraction and hence velocity at 0 in this region at all time during simulation time. Do I still set the values in setFields Dic and how? Thank you Last edited by fredrick; April 7, 2021 at 15:24. Reason: to reduce the font |
