electrostatic force-UDF ?
Hi
Has anybody done modeling taking into account the electrostatic force on charged particles using UDF? |
Re: electrostatic force-UDF ?
The magnitude of the electrostatic force is F_sub_E= qE, where E is the magnitude of the electric field and q is the charge on the particle. The electric field strength must be known. You can set constant or use a UDF to compute or apply a variable electric field.
See http://www.fluentusers.com/fluent6/d...dpm-body-force for a similar example with a magnetic force |

Zhenan,
I'm also modelling taking into account the electrostatic force on charged particles using UDF, I'm at the very starting point. Zhenan, could you tell me which equation u r using? Alamgir |

Hi,
Thanks for your replying. I am using UDF to modeling the Powder Coating System. This is my first time to add electrostatic field and add electric force to charged particles. I added the field using UDS, and want to add the force with UDF. The equation is F = E*Q. Currently I am thinking of the constant Q, and to add this in the function. E will be from the user defined scalar. If it answers your question? Thanks, |

Thanks for your reply. I'm modelling the particle tracking in drinking water with very low volume fraction. Do you count double layer effect on your modelling?

Hi;
My model is simple one. I do not consider that effect. |
