could we simulate fire?
i have a problem of simulating heat radiation of a multi point ground flare with enclosed wall arround. i am thinking of simulating fire from flare with simulation cfd. would it be possible to do it.?
so far i work with simulating internal fluid flow. so i still have no idea about how to do this external fluid flow and "fire" especially.
i found an images of fire simulation using another cfd software below. any idea to do those kind of stuffs?
thanks and regards,
I would say yes - I setup a little file and just ran it out, please see the attached, hopefully it helps. I think my heat output may have been a little high
For fully naturally convected we could run with P=0 at the top and bottom, rather than the velocity on the side that I have.
Hope this helps you out,
Keep in mind that Simulation CFD does not simulate combustion/chemisty so this is going to be a qualitative study.
To allow some radiation to 'emit' from the fire you are going to need to use a resistance material to model the basic shape of the flame. The resistance model does allow for the energy in the zone of the fire to radiate away. This resistance is going to have a low FAR value and a higher default conductivity value.
If you provided more of a diagram of your setup we could talk about more specifics.
