Discrete Phase model
Hi All,
I am using Discrete phase model for a slurry pump to evaluate erosion of walls because of discrete particles entering the domain. Initially I used maximum number of steps in tracking parameters panel as 5, with this option, fluent console displayed message as number tracked = 45500, escaped = 0, aborted = 0, trapped = 0, evaporated = 0, incomplete = 45500 Later I started increasing the maximum number of steps in tracking parameters panel to 20000, then fluent is giving number tracked = 45500, escaped = 16675, aborted = 9494, trapped = 0, evaporated = 0, incomplete = 28825 I am not clear why I am getting aborted tracks in the case? Can anybody suggest me is there any better way to reduce the incomplete and abort tracks. Thanks & Regards Hari Prasad |

[QUOTE=hari_ls;215264]Hi All,
I am using Discrete phase model for a slurry pump to evaluate erosion of walls because of discrete particles entering the domain. Hari, i new and i'm curious why use discrete phase for slurry flow. the theory guide state assumption for discrete phase is that the dispersed second phase occupies a low volume fraction. and isnt slurry flow a dense flow and need to be model by mixture model or Eulerian model?
