I have been experimenting with using Autodesk CFD to investigate facade/ cladding pressures on a (rectangular) building, comparing results with cladding/ facades pressures pressures from design codes and wind tunnel results.
I understand the complexities and difficulties in what I am doing generally and am really exploring at the moment.
From my introductory understanding of CFD from uni and reading around in the literature I understand that the pressures the various turbulence model produce are 'mean' pressures. Papers etc. are always very explicit in referring to 'mean' whenever talking about velocities/ pressures using these techniques. In cladding design one is interested in peak pressures - this is what the design codes and wind tunnel testing give you to design with.
I wonder whether anyone might be able to provide insight, or might have a good reference for further reading, on the possible relationship between peaks and means in these theories? I am not too strong on statistics but is it something that can be derived? It feels like it ought to be.
