Abstract

Çeşitli endüstriyel ve evsel uygulamalar için sıcak hava üretiminde kullanılan havalı güneş kollektörlerinin (SAC) termal verimliliğini arttırmak için genellikle kollektör geometrisi ve akış modelleri üzerine çalışmalar yapılmaktadır. Jet çarpmalı hava kollektörlerinde (JIPSAC) yutucu plaka ve nozulun geometrik şekli, ısıl performansı önemli bir ölçüde etkilemektedir. Bu çalışmada jet çarpmalı havalı güneş kollektöründe ısıl verimliliğini artırmak için yarı küresel yüzeyli emici plaka (HAP) ve dairesel konik nozul (CTN) çifti önerilmiştir. Konik dairesel nozuldan geçen jet akışlı havanın yarım küre şekilli absorber plakaya çarpmasının ısıl verime etkisini incelemek için deneysel çalışma yapılmıştır. Deneysel sonuçları karşılaştırmak için oluşturulan modelin Ansys Fluent 19.2 versiyonu kullanılarak CFD analizi yapılmıştır. Akış fiziğini görselleştirmeye yardımcı olmak için basınç ve hız akım çizgilerinin konturları sunulmuş ve tartışılmıştır. Deneysel ve sayısal analizlerden, yarı küresel emici plaka ve dairesel konik nozul çifti (HAP-CTN) kullanılan jet çarpmalı havalı güneş kollektörünün ısıl verimliliğinin, düz yutucu plakalı jet çarpmalı havalı güneş kollektörüne kıyasla ortalama çıkış sıcaklığı üzerinde %12.33 lük bir artış sağladığı görülmüştür. HAP-CTN çifti kullanılan JIPSAC’ da aynı kombinasyonlar için yapılan deneysel çalışmada kollektörün en yüksek ortalama verimi, 0.0185 kg/s kütlesel debide %24.5 ve en yüksek ortalama kollektör çıkış sıcaklığı 47.8 oC olarak tespit edilmiştir.

Abstract

In order to increase the thermal efficiency of solar air collectors (SACs) used in hot air production for various industrial and domestic applications, studies are generally carried out on collector geometry and flow models. In jet impinging air collectors (JIPSAC), the geometric shape of the absorber plate and nozzle significantly affects the thermal performance. In this study, a hemispherical surface absorber plate (HAP) and circular tapered nozzle (CTN) pair are proposed to increase the thermal efficiency of a jet-impeding solar air collector. An experimental study was carried out to examine the effect of the jet flow air passing through the circular tapered nozzle hitting the hemispherical absorber plate on thermal efficiency. To compare the experimental results, CFD analysis of the created model was performed using Ansys Fluent 19.2 version. The contours of pressure and velocity streamlines are presented and discussed in order to help visualize the flow physics. From experimental and numerical analysis, it has been observed that the thermal efficiency of the jet impingement solar air collector using hemispherical absorber plate and circular tethered nozzle pair (HAP-CTN) provides a 12.33% increase on the average outlet temperature compared to the jet impinging solar air collector with flat absorber plate. In JIPSAC where HAP-CTN pair is used, in the experimental study conducted for the same combinations, the highest average efficiency of the collector was determined to be 24.5% and the highest average collector outlet temperature was 47.8 oC at a mass flow rate of 0.0185 kg/s
