Space charge density in ElectroStaticPrecipitator
Gentlemen:
I am simulating the effect of electric field in an electro static precipitator. For your quick perusal, the governing equations for electrostatis is written below: 1. E= Grad (V), and 2. Div(grad V)= (Total space charge density) / (Dielectric const of air) where V is the applied electric potential, and E is the electric field CFX has provisions to solve Poisson Equations. I would like to know how to setup the varying space charge density effect? I seek advice from all of you. Regards, Vijay

Use quasistatic variables coupled with 'no convection' differecing scheme.
