I would that others paid as much attention to Inco as you
as to the comment about the sink affecting the source, is that not the purpose ?
it is precisely your PCA (Apca ?) that is so difficult with the 6000; semi-impingement, flow bypass, huge swept area, thick bp
anything you select is no more than that, a selection
to have a realistic basis some parametric modeling is needed to establish the sensitivity to source size (uniform flux IS assumed)
you are doing it backwards ? (do I understand ?)
