Default Cross section and surface area factor
Posts: n/a
Hi,I am working on my pos-graduate work and i need a little help. I am using the particle transport model and particle no spherical.

Can anyone let me know how the CFX 4.4 use cross section factor and surface area factor in the particle transport model, a time that this model assumes that the particles are spherical?

In accordance with the solver manual these factors must multiply the cross section and surface area of the sphere to obtain the correct cross section and surface area of the particle. Ok, but where and when?

Thank you in advance.
