Particles faster than fluid
 
Hi ,

The case i am currently working on seems to be quite simple nevertheless i find a probelm which is keeping me from having coherent results.

The case is the flow of a fluid (air) in a pipe . There are heavy particles carried by the flow. When i show the display of the particles velocity i find that the particles reach a higher speed than the fluid which can not be correct.

This problem is delaying me and since it is gonna be soon the end of my internship and I need to solve this problem. Please if someone has ever encountered this kind of problem and have found the solution...

Thanks for your help

Hi, yomanu,
We have to know what multiphase flow model is used in the simulation and more detail about the model and the results.

I don't know which multiphase model would be the best .The guide tell to use mixture or eulerian but i have troubles defining it...and the results still show that the particles are faster than the fluid.
Thanks
