Your comment upstream about the mass flow being to the left of the effy. peak sounds intriguing. Are there any references (eg text books) where I can read more about this? Regarding the areas of the bellmouth, I was actually thinking of the area where gas enters from the smokebox, i.e the difference between the whole bellmouth area and the area taken by the downstream petticoat or nozzle. Another query, is where you say that the smokebox gas cools down as it passes through the system. This is true, but the steam will also heat up, and will this compensate for the cooling effect.
