Hello


As i don't know the details about your ventilation case, I cant really say about your code regarding concentration calculation.



Regarding BFS case, I extracted particle ID,...

Hello



I don't think the gravity in -y direction is right. If you look at the experimental set-up of Fessler & Eaton, the gravity is acting in direction of flow (setup is held vertically in...

Hello

Have you tried to run it in 3D? Because sometimes the 2D condition will make the problem unphysical when I simulate some cases with OpenFOAM


Yes , I tried with 3-D cases using...

-My case setup looks fine. Flow is fully developed and flow seems to be converged as initial residuals of all fluid parameters are below the 1*e-3 expect pressure. I do believe that my fluid flow...

Thank you so much for your answers.





-yes the case is 2-D case. As you said the particle should move in both direction of grad(k), but I can not see my particles dispersing in span-wise...

Hello Oswald,


Thanks for your reply!


Yes, I did simulated the case with and without dispersion model.I cannot see major difference in particle motion and its dispersion along span (y-axis)....

Exclamation particle-laden flow simulation using DPMFoam: turbulent dispersion is not heppening

Hello All,


I am trying to simulate patricle-laden backward facing step (BFS) case using DPMFoam solver in version OpenFoam-v1912. The particles are injected at inlet with speed of 10.5 m/s along...
