Colleagues,
I am attempting to model a clerestory building. On the lower roof
there are a number of solar chimneys that rise above the roof but not so
high as the peak of the clerestory. I am struggling a bit with how to
estimate the wind pressure coefficients (Cp values) of the chimney tops
so that I can calculate the wind-driven part of their air flow. I have
used the TNO CpGenerator tool to obtain Cp values for the roof surfaces
themselves. Does anyone have any experience or suggestions as to how Cp
might vary for positions above the lower roof surface? Any suggestions
would be appreciated.
Kind regards,
David

PS if my explanation of the building configuration is unclear, please
let me know and I would be happy to email a sketch of what I am trying
to model.
