Is there a way to to calculate relative velocity of the particles with respect to fluid,in the DPM model? or how does fluent6 calculates particle reynolds number?
Appreciating all suggestions and help. kulwinder |

Hi
Good question! of course you can obtain this value, I don't know if there is already a macro implemented but you can write a UDF. See the example for define DPM scalar update. Best regards Alex Munoz |

hi alex,
Thanks for your fast and helping response. I need relative velocity at the particle position,and i have access to the fluid velocity at the nodes and cell centroid ,but then i have to interpolate this velocity to the particle position. Interpolation wil make my code long and my fluent run slow. But I have found one macro DEFINE_DPM_DRAG where fluent passes particle Reynolds number to the macro, I will try manupulating this opportunity to my use. Once again I appreciate your help. Best Regards kulwinder |
