Abstract

Çalışmada, Dh jet giriş genişlikli kanallardaki düz ve üçgen basamak modelli yüzeylerden olan ısı transferi üç adet hava jeti akışı kullanılarak araştırılmıştır. Araştırmalar, sayısal olarak sürekli ve üç boyutlu k-ε türbülans modeli kullanılarak Ansys-Fluent bilgisayar programıyla gerçekleştirilmiştir. Kanal yüzeyleri adyabatik olup yalnızca model yüzeylerinde sabit ısı akısı bulunmaktadır. Çalışmanın sonuçları literatürde bulunan çalışmanın sayısal ve deneysel çıktılarıyla karşılaştırılmış ve uyumlu oldukları belirlenmiştir. Sonuçlar, her bir model yüzeyi için ortalama Nu sayısı ve yüzey sıcaklığının değişimi olarak verilmiştir. Farklı Re sayıları ve H/Dh oranlarında model yüzeyleri için kanal boyunca jet akışın hız-akım ve sıcaklık konturu dağılımları değerlendirilmiştir. Re=10000 için H/Dh=3’de düz basamak desenli model yüzeyinin Nuo sayısının, üçgen basamaklı yüzeyden %45,18 daha yüksek olduğu belirlenmiştir.

Abstract

In study, heat transfer from flat and triangular step pattern facets in channels with Dh jet inlet width was investigated using three air jet streams. The studies were carried out with the Ansys-Fluent computer program using the numerical time-independent and three-dimensional k-ε turbulence model. The channel facets are adiabatic and only the model facets have a constant heat flux. The outcomes of the work were matched with the scalar and empiric outcomes of the work in the litterateur, and it was achieved that they are comparable. The outcomes are performed as the mean Nu number and diversity of facet temperature for each model facet. Velocity-flow and temperature contour dispersions of the jet flow throughout the duct were commented for the model facets with distinct Re numbers and H/Dh ratios. It was interpreted that the Nuo number of the flat step patterned model facet at H/Dh=3 for Re=10000 is 45.18% higher than the triangular step facet.
