Experimental and numerical study of turbulent air flow around array of domes over a flat roof

In this paper turbulent air flow around a model of flatroof with three hemispherical domes is studied. Windtunnel measurements are conducted using a single hotfilmprobe. In addition, numerical simulation isperformed using a discretized code and for turbulencemodeling the RNG k-ε model is used. The streamwisevelocity profiles are compared with the wind tunnel dataat several locations over and between the hemisphericaldomes. Good agreement is observed between thesimulated velocity profiles over the hemisphericaldomes. Using the validated numerical solution, the flowpattern at various planes around the model are presentedand discussed.
