how to define the Static bed of height of fluidized bed in STAR-CCM+

Dear All

i do not know how to define bed height in STAR+
with the solid particle size in fluidized bed

thank you

I don't think you define this value. You define a part you would like to fill with particles through geometry or a table injector. That geometry would have the height you want.

how to do that in STAR-CCM+, Do you have any tutorial on fluidized bed modeling in STAR-CCM+

No, I don't, but the user guide has an excellent series of pages on different DEM injectors. You probably want to look at the first one, the lattice injector.

My question is how to do that for fluidezed bed modeling in STAR-CCM
how to do that for static bed height.I am using Eulerian-Eulerian Model in star-ccm+.

thank you

Oh, I guess I assumed you were using DEM for a fluiditized bed, that makes more sense to me than using EMP. I'm not sure how you would do it for EMP, I'm guessing you just need to define a volume fraction or mass fraction for the domain that contains your bed.
