Bu çalışmada, kare desenli alüminyum soğurucu yüzeye sahip bir güneş hava kollektörünün HAD (Hesaplamalı Akışkanlar Dinamiği) analizleri yapılmıştır. Güneş hava kollektörünün verimliliğini arttırmak için kare desenli, pürüzlü bir alüminyum soğurucu yüzey kullanılmıştır. Kollektör içerisindeki çalışma havası, kollektörün sağ, sol ve alt kenarlarından, 15mm aralıklı ve 5mm çapında delikler yardımıyla çekilmektedir. Isı transferi ve hava akış özelliklerinin incelenmesi amacıyla kenar hava alıklı bir güneş hava kollektörünün HAD analizleri yapılmış, farklı ışınım ve kütle debileri altında sistemin optimum çalışma aralıkları belirlenerek karşılaştırılmıştır. Alüminyum kare yapılı kollektörün, 600 W/m², 800 W/m², 1000 W/m², 1200 W/m² ışınım, 0.01-0.015 kg/s kütle debileri ve 20 °C sabit hava giriş sıcaklığı için termal analizleri gerçekleştirilmiş ve çıkan havanın sıcaklık değerleri bulunmuştur.

Numerical Analysis on Solar Air Collector provided with Square Patterned Absorber Surface

Öz

In this study, CFD (Computational Fluid Dynamics) analysis of the solar air collector were carried out. An aluminum absorber surface with a square geometry is used to increase the thermal efficiency of the solar air collector. The working air inside the collector is drawn in with the help of holes with a diameter of 5mm at 15mm intervals on the right, left and bottom edges of the collector. CFD analysis of the solar air collector were performed to examine the heat transfer and air flow properties, and the optimum operating ranges of the system were determined and compared under different radiation and mass flow rates. Thermal analysis of the square patterned aluminum absorber collector were carried out for 600 W/m², 800 W/m², 1000 W/m², and 1200 W/m² radiation at 0.01-0.015 kg/s mass flow rates and 20°C constant air inlet temperature and the temperature values of the outlet air has been obtained.
