Abstract

Bu çalışmada çarpan jet ile soğutmada parametrelerin etkisini belirlemek için Yanıt Yüzey Yöntemi (YYY) ile sayısal optimizasyon yapılmıştır. Nozul sayısı, kanat uzunluğu, kanat geometrisi ve nozul-yüzey mesafesi (H) faktörlerinin etkisi araştırılmıştır. Yanıt değişkeni olarak sıcaklık farkı alınmıştır. Sonuçta en etkin parametre kanat uzunluğu olarak elde edilmiştir. Optimum sonuçlar; nozul sayısı için 5, kanat uzunluğu için 1.5 cm, kanat geometrisi olarak silindir ve H için 2 cm olarak elde edilmiştir. Ayrıca, yanıt değişkeni olan sıcaklık farkı için bir matematiksel model geliştirilmiştir.

Numerical optimization of geometric parameters in impinging jet heat transfer: Response surface methodology

Abstract

In this study, numerical optimization was carried out with the Response Surface Method (RSM) to determine the effect of parameters in impinging jet cooling. The effects of nozzle number, fin height, fin geometry and nozzle to surface distance (H) were investigated. The temperature difference was taken as the response variable. As a result, the most effective parameter was obtained as the fin height. Optimal results; 5 for the number of nozzles, 1.5 cm for the fin height, the cylinder fin geometry and 2 cm for H distance. In addition, a mathematical model has been developed for the temperature difference determined as the response variable.
