Öz

Bu çalışma, kare kapalı kutu içindeki
ısıtılmış eğimli eliptik silindirin doğal taşınımla ısı geçişini inceleyebilmek
için iki boyutlu sayısal olarak analiz edilmiştir. Çalışmada kare kapalı
kutunun yüzeyleri soğuk, eliptik silindir ise ortamın tek ısı kaynağıdır.
Analiz yapılırken eliptik silindir için üç farklı eğim açısı (
θ=0°, 45°, 90°), eliptik silindirin dört farklı
en/boy oranı (b/a=0.25, 0.5, 0.75, 1.0) ve dört farklı Rayleigh sayısı (Ra=104,
105, 106, 107) göz önünde bulundurulmuştur.
Sistemde bulunan havanın termofiziksel özelliklerinin sabit olduğu ancak
yoğunluğun Boussinesq yaklaşımı altında sıcaklıkla değiştiği ve akışkanın
hareketinin yoğunluk farkından dolayı gerçekleştiği varsayılmıştır. Çözümlerden
elde edilen veriler doğrultusunda eliptik silindir üzerinden hesaplanmış
ortalama Nusselt sayısı grafiklerde verilmiştir. Ayrıca eş sıcaklık eğrileri ve
akım çizgileri de sunulmuştur.
