Bu çalışmada, içerisinde bölmeler bulunan zigzag bir kanalda Al2O3-su nanoakışkanın termo-hidrolik performansı sayısal olarak incelenmiştir. Kütle, momentum ve enerji eşitlikleri sonlu hacim yöntemi ile ayrıklaştırıldı ve iterasyonlar SIMPLE algoritması ile çözülmüştür. Reynolds sayısı (200 ≤ Re ≤ 1600) ve partikül hacim oranı (0.01 ≤ φ ≤ 0.03) değiştirildi ve diğer parametreler sabit tutulmuştur. Zigzag kanalın alt ve üst yüzeyleri sabit sıcaklıkta tutulmuş ve kanal boyunca Nusselt sayısı ve sürtünme faktörü hesaplanmıştır. Parametrelerin, akış ve ısı transferi üzerindeki etkilerini gözlemlemek için kanal içerisinde hız ve sıcaklık görüntüleri elde edilmiştir. Sonuçlar, artan partikül hacim oranı ve Reynolds sayısı ile ısı transferinin iyileştiğini, sürtünme faktörünün hafif şekilde arttığını göstermiştir. En iyi termo-hidrolik performans Re=1400 ve φ = %3’de yaklaşık 1.15 olarak elde edilmiştir.

INVESTIGATION OF THERMO-HYDRAULIC PERFORMANCE OF NANOFLUIDS IN A ZIGZAG CHANNEL WITH BAFFLES

Abstract

In this study, the thermo-hydraulic performance of Al2O3-water nanofluid in a zigzag channel with baffles were numerically investigated. The mass, momentum and energy equations are discretized with finite volume approach and iterations are solved with SIMPLE algorithm. Reynolds number (200 ≤ Re ≤ 1600), and nanoparticle volume fraction (0.01 ≤ φ ≤ 0.03) were changed, and other parameters kept constant. The lower and upper zigzag surfaces of the channel were kept at constant temperature, and the Nusselt number and friction factor along the channel were calculated. The velocity and temperature contours in the channel were obtained in order to observe the effects on flow and heat transfer of the paramerers. The results shown that the increasing particle volume fractions and Reynolds numbers improved the heat transfer, while the friction factor increased slightly. The best thermo-hydraulic performance was obtained at Re = 1400 and φ = 3% as approximately 1.15.
