    "abstract": "Çarpan jetler, iyi bir ısı transferi performansı sağlamaları nedeniyle genellikle sanayide elektronik ekipmanların\r\nısıl problemlerini çözmek için kullanılırlar. Bu çalışmada, tek bir hava jeti akışı kullanılarak bir tarafı açık, üç tarafı\r\nkapalıdikdörtgensel bir kanal içerisindeki beş adet dikdörtgen ve yamuk desenli bakır plakalı yüzeylerin soğutulması sayısal\r\nolarakaraştırılmıştır. Sayısal hesaplamalar, zamandan bağımsız, üç boyutlu Navier-Stokes ve enerji denkleminin k-ε türbülans\r\nmodelini de dikkate alarak Ansys-Fluent 17.0 bilgisayar programı kullanılarak çözülmesiyle gerçekleştirilmiştir. Çalışma akışkanı\r\nolarak 300 K giriş sıcaklığında hava kullanılmıştır. Kanalın üst ve alt yüzeyleri adyabatik iken kare ve yamuk desenli yüzeylere\r\nsabit1000 W/m2’ lik ısı akısı uygulanmıştır. Çalışma, Re sayısının (Re) 4000, 6000, 8000 ve 10000 ve jet-plaka arası\r\nuzaklığın (H/Dh)4, 6 ve 10 olduğu değerler için yapılmıştır. Sayısal sonuçların literatürde var olan çalışmanın sayısal ve\r\ndeneysel sonuçları ile uyumlu oldukları görülmüştür. Sonuçlar, her bir desenli yüzey için ortalama Nusselt sayısı (Nu) ve yüzey\r\nsıcaklığının değişimiolarak sunulmuştur. Jet akışın sıcaklık, hız konturu ve akım çizgileri dağılımları farklı Re ve\r\nH/Dh oranları için ayrıcaaraştırılmıştır. Yamuk desenli yüzeylerin ortalama Nu sayısı değerinin H/Dh=10 ve\r\nRe=10000 için dikdörtgen desenli yüzeylerden % 17.56 daha fazla olduğu bulunmuştur.",

    "english_abstract": "Impinging jets are usually used to solve thermal problems of electronic components in industry due to providing a good heat transfer performance. In this study, cooling of copper plate with five square and trapezoid patterned surfaces inside a rectangular channel comprising of one open and three blocked sides was numerically researched by using a single air jet flow. The numerical computations were performed by solving a steady, three-dimensional Navier-Stokes equation and an energy equation by using Ansys-Fluent 17.0 software program with k-ε turbulance model. Air was taken as working fluid with inlet temperature of 300 K. A constant heat flux with 1000 W/m2 was applied to square and trapezoid patterned surfaces while the top and side surfaces were adiabatic. The study was carried out for different Reynolds numbers (Re) of 4000, 6000, 8000 and 10000 and different jet-to-plate distances (H/Dh) of 4, 6, 10. The numerical results agreed well with the numerical and experimental datas of study existed in literature. The results were presented as the variations of the mean Nu numbers and surface temperatures for each square and trapezoid patterned indentation surface. The temperature, velocity contur distributions and stream lines of jet fluid flow were also investigated for different Re numbers and H/Dh ratios. It was found that average Nu number value of trapezoid patterned surfaces was higher 17.56% than that of square surfaces for H/Dh=10 and Re=10000.",
