Engellerle Donatılmış Oluklu Bir Kanal İçerisindeki Akış ve Isı Transferi Karakteristiklerinin Sayısal Olarak İncelenmesi

Bu çalışmada engellerle donatılmış oluklu bir kanalın türbülanslı akış ve ısı transferi karakteristikleri sayısal olarak incelenmiştir. Engeller kanal alt yüzeyine akışa göre üç farklı açıda (450, 900 ve 1350) yerleştirilmiştir. Hız ve türbülans kinetik enerji konturları ve ortalama Nusselt sayısı, sürtünme faktörü, basınç düşüşü ve termal-hidrolik performans değerlendirme kıstas dağılımları sunulmuştur. En yüksek Nusselt sayısı ve performans değerlendirme kıstası, sırasıyla, =450 =900 and =1350 oluklu-engelli kanallar için elde edilmiştir.

Numerical Investigation of Flow and Heat Transfer Characteristics in a Corrugated Channel Equipped With Obstacles

In this study, the turbulent flow and heat characteristics of a corrugated channel equipped with obstacles were investigated experimentally. The obstacles were placed on the bottom wall of the channel at three different angles of =450, 900 and 1350 with respect to the incoming flow. The velocity and turbulence kinetic energy contours and average Nusselt number, friction factor, pressure drop and thermal-hydraulic performance evaluation criteria distributions were presented. The highest Nusselt number and performance evaluation criteria values were obtained, respectively, for corrugated channels with obstacles with =450 =900 and =1350.
