A numerical study on performance improvement in boiling heat transfer via dichloromethane-based nanofluid utilization
Öz: Nanofluids are colloidal suspensions and have been utilized frequently in heat transfer implementations ranging from heating to cooling. In this study, for numerically specifying the influence of nanoparticle addition inside the base fluid on pool boiling heat transfer, a series of numerical analyses were performed by using hexagonal boron nitride and dichloromethane as nanoparticle and base fluid material, respectively. The nanofluid solution was prepared by doping hexagonal boron nitride nanoparticles into the dichloromethane at the rate of 1.0% (vol.) and Sodium Dodecyl Benzene Sulfonate was added into this solution to prevent nanoparticle compilation during operation. Computational Fluid Dynamics (CFD) approach was preferred and ANSYS Fluent software was used for numerical analysis. In order to be able to make comparison, analysis was performed both dichloromethane and hexagonal boron nitride nanoparticles containing dichloromethane, i.e. nanofluid, solutions. Vapour volume fractions, velocity vectors, and contours for each working fluid were determined and discussed.
Anahtar Kelime: Diklorometan esaslı nanoakışkan kullanımıyla kaynama ısı transferinde performans iyileştirme üzerine sayısal bir çalışma
Öz: Nanoakışkanlar koloidal süspansiyonlardır ve ısıtmadan soğutmaya kadar birçok ısı transfer uygulamasında sıklıkla kullanılmaktadır. Bu çalışmada temel akışkan içerisine nanoparçacık ilavesinin havuz kaynama ısı transferi üzerindeki etkisini sayısal olarak belirlemek amacıyla nanoparçacık ve temel akışkan malzemeleri olarak sırasıyla hekzagonal bor nitrür ve diklorometan kullanılarak bir dizi sayısal analiz gerçekleştirilmiştir. Nanoakışkan çözeltisi, hekzagonal bor nitrür nanoparçacıklarının diklorometan ile hacimce %1.0 oranında karıştırılmasıyla hazırlanmış ve sistemin çalışması esnasında nanoparçacıkların topaklanmasını önlemek için bu çözeltiye Sodyum Dodesil Benzen Sülfonat ilave edilmiştir. Hesaplamalı Akışkanlar Dinamiği (HAD) yaklaşımının kullanıldığı bu çalışmada, sayısal analizler için ANSYS Fluent yazılımı kullanılmıştır. Karşılaştırma yapabilmek için, hem diklorometan hem de hekzagonal bor nitrür nanoparçacıkları içeren diklorometan (nanoakışkan) çözeltileri için analizler yapılmıştır. Her iş akışkanı için buhar hacim fraksiyonları, hız vektörleri ve hız konturları belirlenerek elde edilen sonuçlar irdelenmiştir.
