Endüstride birçok alanda kullanılmakta olan elektrosprey soğutma alanında son yıllarda keşfedilmeye başlanan bir konudur. Bu çalışmada literatürde hakkında oldukça kısıtlı çalışmalar bulunan elektrosprey soğutma ile mekanik sprey soğutmanın ısı alıcı üzerindeki soğutma performansı irdelenmiştir. Aynı şartlarda elektrosprey ile gerçekleşen ısı transferinin verileri deneyler yapılarak elde edilirken, mekanik sprey soğutma verileri Ansys Fluent CFD programı kullanılarak elde edilmiştir. Yapılan deneysel ve sayısal çalışmanın sonucunda daha küçük partikül çapı ve yüklü damlacıkların elde edildiği elektrosprey soğutmada mekanik sprey soğutmaya göre yaklaşık %15 daha iyi bir ısı transfer performansı gösterdiği belirlenmiştir. Elektrosprey metodunda, mekanik spreye göre 3,2 kW/m2 ısı akısında %13, 2,59 kW/m2 ısı akısında %14, 1,88 kW/m2 ısı akısında ise %17 daha iyi soğutma elde edildiği görülmüştür.

Comparison of Electrospray And Mechanical Spray Atomization Cooling Performances on Heat Sinks

Öz

In recent years, it is a topic that has been discovered in the field of electrospray cooling, which is used in many areas in industry. In this study, the cooling performance of electrospray cooling and mechanical spray cooling on the heat sink, about which there are very limited studies in the literature, were examined. In the same conditions, the data of heat transfer with electrospray were obtained by conducting experiments, while the data of mechanical spray cooling were obtained by using Ansys Fluent CFD program. As a result of the experimental and numerical study, it was determined that electrospray cooling, in which smaller particle diameter and charged droplets were obtained, showed a heat transfer performance approximately 15% better than mechanical spray cooling. In the electrospray method, it was observed that 13% better cooling was obtained at 3,2 kW/m2 heat flux, at 2,59 kW/m2 heat flux %14 and better at 1,88 kW/m2 heat flux %17 compared to mechanical spray.
