Abstract

Mean surface pressures and overall wind loads on hemispherical domes immersed in arnboundary layer were obtained by numerical simulation. The effects of alternative turbulence models,rnReynolds Number and surface roughness were examined and compared with earlier studies. Surfacernpressures on dual hemispherical domes were also calculated for three wind orientations (0 o , 45 o , and 90 o )rnto evaluate flow field interactions. Calculated values were compared to wind-tunnel measurements made inrnequivalent flow conditions.

Key Words

wind loads; computational wind engineering; fluid modeling; hemispherical domes.
