Özet

Bu çalışmada, sınır tabaka içine yerleştirilmiş yarı-elipsoid bir engel etrafındaki türbülanslı akış alanı deneysel ve sayısal olarak incelenmiştir. Rüzgar tünelinde, 150 mm yüksekliğinde atmosferik bir sınır tabaka oluşturularak, akış görüntüleme çalışması ve yüzey basıncı ölçümleri yapılmıştır. Realizable k-ε ve Standard k-ω türbülans modelleri ile akış alanının iki boyutlu sayısal çözümleri elde edilmiş ve sonuçlar deneylerle karşılaştırılmıştır
