Alt Duvarı Dalgalı Kapalı Kare Geometride Yüzey Işınımı ile Doğal Taşınımın Sayısal İncelenmesi

Year 2018, Volume: 18 Issue: 3, 1137 - 1148, 30.12.2018

Abstract

Alt duvarı dalgalı ve tüm duvarlarında aynı yüzey ışınım yayma oranına sahip kapalı kare geometride birleşik doğal taşınım ve yüzey ışınımı sayısal olarak incelenmiştir. Geometride alt duvar ısıtılmış, üst duvar soğutulmuş, dikey duvarlar ise yalıtılmıştır. Sıcak ve soğuk duvarlar izotermal ve sabit sıcaklıkta tutulmuştur. Doğal taşınım için tanımlanan momentum ve enerji denklemi 104≤Ra≤106 ve 0≤ε≤1 alınarak SIMPLE algoritması ile sonlu hacimler kullanılarak Fluent paket programında çözülmüştür. Katılımcı olmayan ortam için yüzeyler arası ışınımla ısı transferi denklemi Discrete Ordinate Metod (DOM) kullanılarak çözülmüştür. Soğuk duvar üzerinden hesaplanan ortalama Nusselt sayısı ve geometride meydana gelen akış değişimleri değişen Rayleigh sayısı, yüzey ışınım yayma oranı, alt duvar dalga sayısı ve dalga genliği için analiz edilmiştir. Dalgalı duvarın dalga sayısı ve genliğinin değişimi aynı şartlardaki düz duvara göre bazı durumlarda ortalama toplam Nusselt sayısında maksimum %8.82 değerinde bir iyileştirme sağlamıştır.
