Validation of the computational fluid–structure interaction simulation at real-scale tests of a flexible 29m umbrella in natural wind flow

Wind-structure interaction simulations of ovalling vibrations in silo groups

“…Such spectra typically do not account for the energy content of the inertial subrange [109]. Furthermore, due to the spatial filtering of LES, a cutoff corresponding to the grid size is also typically observed in the turbulence spectrum [148,167]. In the present simulations, however, the grid size is not uniform in the entire computational domain (cfr.…”

“…This technique is therefore typically used for monitoring purposes or when remedial measures are required to limit excessive wind-induced vibration in an existing structure. Some exceptions exist in academia where simple buildings are built and instrumented in a real environment to perform validation and benchmark studies [167,207,208]. Of course, on site measurements are also performed to obtain realistic information on the wind climate at a specific site.…”

“…In civil engineering, offshore applications such as flow-induced vibrations of offshore risers [49,75,108,289] and ocean current-driven or wave energy converters [52,181,190] have been considered. The study of wind-induced vibrations finally was for a long time focussed on flutter of long suspension bridges [155,190,267] but is also used to investigate flexible membrane structures in wind flows [27,103,167,284,286] and for aeroelastic studies of wind turbine rotors [37,98].…”

“…With a tendency in modern day architecture to build ever lighter and more slender structures, the issue of wind-induced vibrations for this type of structures continuously increases in importance, e.g. [167,285,286].…”

“…This may be cumbersome, however, since a time-consuming iterative study is then needed to obtain the correct configuration of roughness blocks for the specific prescribed ABL profile [167]. Furthermore, these roughness elements are often not very small compared to the building size and therefore have to be removed in the region around the building [148].…”
