Abstract

Bu çalışmada, farklı sıcaklıklardaki kapok izolasyon malzemesinden gerçekleşen ısı akışı, rüzgar hızı karşısında analiz edilmiştir. Isı akışının bir teorik modeli; iletim, ısı yayımı ve ışıma ile kombine edilerek sunulmuştur. Sonlu elemanlar yöntemi, detaylı çalışma amacı ile kullanılmıştır. Çalışmada, teorik sonuçlar ile deneysel sonuçlar arasında iyi bir uyum olduğu görülmüştür

AN INVESTIGATION OF HEAT FLOW THROUGH KAPOK INSULATING MATERIAL

Abstract

The heat transfer process through kapok insulating material at different temperatures against wind speed was analyzed. A theoretical model of heat flow combined with conduction, convection and radiation was presented. The finite element method was used for detail study. Through the experiment, which was accomplished in an artificial climate chamber, it was found there was a good accordance between theoretical results and experimental results

Keywords

Kapok, Finite element analysis, Heat transfer, Warm-keeping, Transient maximum heat flow
