radiation
 
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.

thanks Evan,I know view factor is changing with distance but do you have any idea how? thanks again, john

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.
