NUMERICAL SIMULATION OF STEADY ATMOSPHERIC FLOW FOR FOLDING RETICULATED SHELL

Numerical investigations of folding camping shell structure under steady wind fields have been conducted in this paper using the computational fluid dynamics code Fluent 6.3. The computational domain, the mesh size and turbulent flow model used in the numerical simulation were determined according to the wind tunnel test data. The surface pressure distribution of folding camping shell under different wind directions was obtained. The shape coefficient for the folding reticulated shell was calculated and compared with that obtained from the wind tunnel test, showing good agreement. It can be found from the results that the wind directions have significant influences on the wind load shape coefficient while the wind speed have little effect. The shape coefficient obtained in this study can provide reference for the design of this kind of structure.
