Abstract
Bu
çalışmada kesit alanını değişiminin kanal boyunca ( L=300 mm) gerçekleştiği bir
geçiş bölgesinde yatay ve düşey yöndeki hız dağılımları deneysel olarak
incelenmiştir. Geçiş kanalının giriş ve çıkış kesit oranları 1:2 olup kanalın üst-alt
kenarlarının ve yan kenarlarının kanal ekseni ile yaptıkları açı sırasıyla 
ve 
olarak belirlenmiştir. Geçiş kanalındaki hız taramaları 0<x/L<1
aralığındaki aynı x/L noktalarında yatay ve düşey yönde kızgın tel anemometresi
ile yapılmıştır. Deneysel çalışmada, Reynolds sayısı 1.2x105-5x105
aralığında alınmıştır. Kesit alanı değişiminin akışın hız dağılımı üzerine
etkili olduğu belirlenmiştir.
