In this study, wind and temperature effects of Dicle University Engineering Faculty were investigated numerically. The study was handled in 4 cases. In case the wind blows, respectively, from southeast (front part), northwest (rear part), northeast (right part) and south west (left part) the wind and flow characteristics on the building were examined. The study was carried out with the used ANSYS CFX software program, which is frequently used in computational fluid dynamics applications. In the entrance, wind speed has been taken as 40 m/s. Inlet wind temperature is given as 35 oC. In order to determine the wind directions, satellite images of the building were taken with the used of google maps application. Building surface temperature was determined as 25 oC. Actual dimensions are used for building dimensions. At the end of the study, velocity contours and streamlines were obtained for 4 cases. In addition, were given graphs of average velocity and temperature along a line passing through the middle of the building.

Dicle Üniversitesi Mühendislik Fakültesinin Rüzgâr ve Sıcaklık Etkilerinin Nümerik Olarak İncelenmesi
Öz
Bu çalışmada Dicle Üniversitesi Mühendislik Fakültesinin rüzgâr ve sıcaklık etkileri nümerik olarak incelenmiştir. Çalışma 4 durumda ele alınmıştır. Sırasıyla rüzgârın güneydoğu (ön kısım), kuzeybatı (arka kısım), kuzeydoğu (sağ kısım) ve güney batı (sol kısım)’dan esmesi durumunda bina üzerindeki rüzgâr ve akış özellikleri incelenmiştir. Çalışma hesaplamalı akışkanlar dinamiği uygulamalarında sıklıkla kullanılan ANSYS CFX yazılım programı yardımıyla gerçekleştirilmiştir. Giriş kısmında rüzgâr hızı 40 m/s olarak alınmıştır. Giriş rüzgâr sıcaklığı 35 oC olarak verilmiştir. Rüzgâr yönlerinin tespit edilmesi için Google haritalar uygulaması yardımıyla binanın uydu görüntüleri alınmıştır. Bina yüzey sıcaklığı 25 oC olarak belirlemiştir. Bina boyutları için gerçek ölçüler kullanılmıştır. Çalışma sonunda 4 durum için hız konturları ve akım çizgileri elde edilmiştir. Ayrıca binanın orta noktasından geçen bir çizgi boyunca ortalama hız ve sıcaklık grafikleri verilmiştir.
