Abstract

In the present paper, the effects of wind were calculated numerically in three dimensions for buildings placed in two consecutive different distances. ANSYS-FLUENT 14.0 program was used for numerical calculation. According to meteorological data for Sivas, the average wind speed was determined and. RNG k-ɛ was used as the turbulence model. As a result of the calculations, it was seen that the flow structure and vortex areas around the rear building were affected by increasing the distance between the buildings. In addition, the highest positive pressure coefficients were observed on the front surfaces of the first building and negative pressure coefficients were observed on the B, C and D surfaces. In the rear building, only positive pressure was seen at the roof level, while negative pressure coefficients were obtained for all heights on all other surfaces.

Özet

Bu çalışmada, farklı ara mesafelerde art arda iki yerleştirilen binalar için rüzgarın etkileri üç boyuttasayısal olarak hesaplanmıştır. Sayısal hesaplamada ANSYS-FLUENT 14.0 programı kullanılmıştır. Sivasiçin meteorolojik veriler göz önüne alınarak ortalama rüzgar hızı belirlenmiş ve türbülans modeli olarakRNG k-ɛ kullanılmıştır. Hesaplamalar sonucunda, binalar arasındaki mesafenin artırılmasıyla arka binaetrafındaki akış yapısı ve girdap alanlarının etkilendiği görülmüştür. Ayrıca, ilk binanın ön yüzeylerindeen yüksek pozitif basınç katsayıları oluştuğu, B, C ve D yüzeylerinde ise negatif basınç katsayılarınınoluştuğu gözlenmiştir. Arka binada sadece çatı seviyesinde pozitif basınç görünüyor iken, diğer tümyüzeylerde tüm yükseklikler için negatif basınç katsayıları elde edilmiştir.
