Fortran Code(corona effect)

January 30, 2006, 08:31

Hi

I am working on project related to ESP(electrostatic precipitators). I want to solve corona effect in ESP by using CFX. For that I am developing code(I use fortran) for this corona effect. I want to know that how can I incorporate this code with CFX. If any one solved this type of problem then guide me. Or any suggestion please….

Hi Trushar,

Would you mind describing your model in mathematical terms? It is easy to add simple new models to ANSYS CFX via the ADDITIONAL VARIABLE hook..

Do you want to solve the electrostatic potential? Like in

div (permivitivity * grad (ElecPot) ) = 0

with Dirichlet or Neumann boundary conditions?

For this, you do not even need User Fortran...

Opaque..

Hi Trushar, i am also working on ESP.but i have some difficulties in cfx.because in my case i have to give screen blockages which are surfaces in between domain.so first i have used another software like ideas in that screen blockages option is there.so do u know that how screen bloackge is given in cfx?If u know in another code like fluent then pls also tell me.

Hi
I'm doing the same things currently.
Can you explain me how did you model the corronna effect in CFX
