Periyodik Oluklu bir Kanalda Laminer Pulsatif Akışın Isı Transferi Karakteristiğinin Sayısal Analizi

Abstract

Bu çalışmada, periyodik dalgalı bir kanalda laminar pulsatif akışın hidrolik ve termal davranışları üzerindeki etkileri sayısal olarak analiz edilmiştir. Sayısal çözümler, sonlu hacim yaklaşımı ile analiz yapan FLUENT programı ile gerçekleştirilmiştir. Çalışmada, pulsatif genlik (A), Strouhal sayısı (St), Reynolds sayısı (Re) değiştirilmiş, diğer parametreler sabit tutulmuştur. Dalgalı kanalın alt ve üst yüzeyleri T=350K sıcaklığında korunmuştur. Sayısal sonuçlar, Nusselt sayısı (Nu), sürtünme faktörü (f) ve termo-hidrolik etkinlik (THE) açısından sürekli akış şartları ile karşılaştırılarak sunulmuştur. Pulsatif parametrelerin ve Reynolds sayısının kanal içindeki davranışını gözlemlemek için anlık akış ve sıcaklık dağılımları elde edilmiştir. Çalışma sonuçları, kanal içindeki akışın kanal geometrisinden, pulsatif parametrelerden ve Reynolds sayısından önemli derecede etkilendiğini göstermiştir. Artan Reynolds sayısı ve pulsatif parametreler ile hafif bir basınç düşüşü ile ısı transferinde kayda değer bir iyileşme sağlanmıştır.
