Hello, I'm trying to simulate an Electrostatic Precipitator in Fluent.

I'm familiar using Fluent with aerodynamic, heat transfer and clean room simulations.

However this is my first time using Fluent for this topic. I want to know the steps for this simulation. 

I've downloaded Fluent R2023 in student version and I saw there's a model for "potential/electrochemistry".

Can I use this model for electrostatic simulation? 

I also have read some papers that mentioned about using UDF.
Should I use UDF as well for electrostatic simulation?

 

Thank you

The hard part is adding the field and electrostatic force to the system. The UDF is probably to add a body force to the particles based on the field.

So it means If I want to simulate the Electrostatic, I should add field and electrostatic force to the system.
Can I do that using models "potential/electrochemistry" or "MHD"? 
Do you have any clue what kind of UDF I must use to add body force to the particles? Is it DPM? 
Thank you

DPM would be the main model, and I'd start here  https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v231/en/flu_udf/flu_udf_DPMDEFINE.html%23flu_udf_sec_define_dpm_body_force

Not sure about the electric field. The potential field may be sufficient, I'd avoid electrochemisty and MHD for now.

Alright, thank you so much for the information Rob.
I will discuss with my collegues about this first.
