Investigation of Turbulent Flow Around Circular High-Rise Structure with Various Balcony Design

English (OpenAlex)

In this study, flow fields around circular cross-sectioned high-rise structures with and without balconies have been investigated. Three different balcony heights (h/d1=3, h/d1=3.5, h/d1=4) and three different balcony diameters (35 mm, 40 mm, 45 mm) were considered in the study, with the experiments carried out at a free stream velocity of 15 m/s. In the experimental part of the study, flow visualization around the model (h/d1=3.5) was achieved using the smoke-wire technique in the wind tunnel test section. In the numerical part, the flow patterns around the models, velocity distributions, and pressure coefficients on the balcony surfaces are calculated using the Realizable k-ε turbulence model. The pressure coefficient distributions are directly affected by the position of different balcony heights. When different balcony heights are compared, it is seen that the highest pressure coefficient values are achieved for h/d1=3, while the most critical pressure coefficient values are obtained in the case of h/d1=4.
