Lagrangian particle tracking CFX & Fluent

s.petley · June 3, 2015, 09:25

I was wondering if anyone could explain if there is a difference between the Lagrangian particle tracking models in CFX and Fluent, looking at the solver guide they seem to apply the same physics but I might be wrong?

Cheers

There are differences in models used as forces acting on particles, namely:
-Drag law, Different options available in CFX and Fluent.
-Shear lift force, Only available in Fluent.
-and maybe other physical models...
-for Turbulence dispersion effect, there is slightly different controls in both packages.
Overall I think Fluent solver is richer and more flexible in particle tracking.
But for post-processing there is more limitation on presentation of particle tracking data in Fluent(+ CFD-Post) than CFX (+ CFD-Post).
