Standart Buhar Çevrimi ile Çalışan Bir Soğuk Depoda Hava Hızının Hesaplamalı Akışkanlar Dinamiği ile Analizi

Year 2016, Volume: 12 Issue: 1, 19 - 26, 14.10.2016

Abstract

Bu
araştırmada standart buhar çevrimi ile çalışan bir soğuk depoda şeftalinin
depolanması sırasında hava hızları farklı seviyeler için ölçülmüş ve aynı
zamanda hesaplamalı akışkanlar dinamiği (HAD) ile Ansysy Fluent pogramı
kullanılarak hava hızı dağılım modelleri oluşturulmuştur. Ölçüm ve model hava
hızı değerleri karşılaştırılarak depo için modelin geçerliliği test edilmiştir.
Ayrıca depolama sırasında hava hızı ölçüm değerleri ile modellemeden elde
edilen değerler karşılaştırılarak oluşturulan HAD hava hızı dağılım
modellerinin geçerliliği istatistiksel açıdan değerlendirilmiştir.
Modellemeden elde edilen değerler ile ölçümden elde eldilen değerler
arasındaki fark ortalama olarak 0.49 m/s olarak saptanmıştır. HAD Model ile
ölçümler arasındaki tahmin hatası ölçüm sayısının sınırlı olması ve modellemede
sınır koşullarının belirlenmesindeki zorluklardan dolayı %39.73 olarak
hesaplanmıştır.
