Does anybody know how fluent accounts for view factor in radiation model? I'm modeling a hot particle approaching a cold plate and I have to consider radiation.what is the view factor for this problem?

Thanks , John

I'm not sure that FLUENT can do this. I think it only does surface-to-surface radiation, which we have used and which works acceptably. The view factor between a moving particle and fixed plate will be constantly changing.

Try looking at "http://mohican.me.utexas.edu/~howell/", which has a large catalog of view factor equations. You should find one that matches your configuration.
