Abstract
In this study, melting of aluminum metal in a silicon
carbide pot was explored theoretically by utilizing solar rays concentrated
through a dish reflector. Based on the climatic conditions of Istanbul, İzmir,
Antalya and Mersin cities, calculations were made for 5 different dish and
receiver diameters and the potential amount of molten aluminum was determined.
The temperature change in the receiver depends on the condensation rate, direct
sunlight and receiver material properties. In this case, the amount of melting
aluminum was found to have an effect at very high rates. As the condensation
rate increases, the temperature in the pot (on the receiver) increases and the
aluminum smelting potential may increase even though the receiver size
decrease.

GÜNEŞ ENERJİLİ PARABOLİK ÇANAK SİSTEMDE ALÜMİNYUM METALİNİN ERİTİLMESİNİN TERMAL VE MATEMATİKSEL ANALİZİ
Abstract
Bu çalışmada çanak yansıtıcı vasıtasıyla
yoğunlaştırılmış güneş ışınlarından faydalanılarak silisyum karbür potada
alüminyum metalinin ergitilmesi teorik olarak incelenmiştir. İstanbul, İzmir, Antalya ve Mersin şehirlerinin
iklim koşulları temel alınarak 5 farklı çanak ve alıcı(pota) çapı için
hesaplamalar yapılmıştır ve potansiyel ergitilebilir alüminyum miktarı
belirlenmiştir. Alıcıdaki sıcaklık değişimi yoğunlaştırma oranına, direkt gelen
güneş ışınlarına ve alıcı malzeme özelliklerine bağlıdır. Bu durumun eritilecek
alüminyum miktarına çok yüksek oranlarda etkisi olduğu görülmüştür. Yapılan
hesaplamalar sonucunda yoğunlaştırma oranı arttıkça potadaki(alıcıdaki)
sıcaklık artmış, alıcı boyutu küçülmesine rağmen alüminyum ergitme
potansiyelinin artabileceği görülmüştür.
