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
