Can anybody suggest me how the quoted liene is possible,
"In versions prior to ANSYS FLUENT 13, one drawback of the dense discrete phase model was that it did not prevent the actual concentration of particles from becoming unphysically high. Hence, the model had only a limited applicability to flows close to the packing regime, such as fluidized bed reactors. To overcome this, ANSYS FLUENT now applies a special treatment to the particle momentum equation as soon as the particle volume fraction exceeds a certain user specified limit. Thus, the unlimited accumulation of particles is prevented. In turn, this will allow you to simulate suspensions and flows like bubbling fluidized bed reactors, operating at the packing limit conditions, allowing for polydispersed particle systems."
I am facing the same problem my particles are very high.
