Döner tip rejeneratör diferansiyel denklemlerinin çözümü için en uygun sınır şartlarının belirlenmesi

Öz

Döner tip rejeneratörler, atık ısıdan faydalanarak enerji tasarrufu sağlanması amacıyla iklimlendirme sistemleri gibi düşük sıcaklık uygulamalarında da kullanılmaktadır. Bu çalışmada, döner tip rejeneratörler için geliştirilen matematiksel model sonlu farklar yöntemi kullanılarak çözülmüş ve bu yöntemde kullanılacak sınır şartlarının çözüm üzerindeki etkileri araştırılmıştır. Periyotlar arası geçiş noktalarında iki farklı sınır şartı kullanılmıştır. Bir periyottan diğer periyoda (sıcak periyottan soğuk periyoda ya da soğuk periyottan sıcak periyoda) geçiş noktalarında, sınır şartı olarak doğrudan akışkan sıcaklığını vermek yerine, bu noktalarda akışkanda iletimle ısı transferi olmadığı varsayımının daha doğru sonuçlar verdiği ortaya konmuştur.
