Abstract

Dairesel bir tüp içindeki ters kavisli kesitli bükülmüş bantların, ısı transferi, basınç düşüşü ve performans değerlendirme kriterleri (PDK) üzerindeki etkileri ANSYS Fluent v18 yazılımı kullanılarak sayısal olarak incelenmiştir. Analizler, üç farklı ters kavis çapının boru çapına oranını (0.872, 0.647 ve 0.554) ve iki farklı büküm oranını (3.0 ve 4.0) içermektedir. Çözümlemeler 5800 ila 30000 Reynolds sayısı aralığında hava kullanılarak gerçekleştirilmiştir Dış boru duvarına sabit ısı akışı uygulanmıştır. Sonuçlar, ısı transfer performansının büyük ölçüde bükümlü bant geometrisine bağlı olduğunu göstermiştir. Ters kavisli kesite sahip bükülmüş bandın Nusselt sayısı %0 ila %85 aralığında ve sürtünme faktörü %123 ila %238 aralığında düz borudan daha yüksek bulunmuştur. Ters kavisli bükülmüş bandın PDK değeri çalışılan Reynolds sayısı aralığında 0.75 ile 1.23 arasında bulunmuştur. En yüksek PDK değeri, maksimum çap oranı ve minimum büküm oranı için 5849 Reynolds sayısında 1.23 olarak hesaplanmıştır. Ters kavisli bükümlü bant ile teçhiz edilmiş tüpün Nusselt sayısı, sürtünme faktörü ve PDK'sı için istatistiksel korelasyonlar geliştirilmiştir.
