Abstract

Bir siklon ayırıcıda düşük basınç düşüşü ve yüksek partikül tutma verimi gerçekleşmesi istenir. Bu bakımdan siklon ayırıcıların performanslarının tayininde kritik çap önemli bir parametredir. Performansa etkiyen önemli parametrelerden biri de hızdır. Bu çalışmada giriş hızı değişiminin etkisini tahmin için kullanılan ve literatürde mevcut matematik modellerden 10 tanesi yine literatürde mevcut hız değişimini inceleyen yaklaşık 120 farklı deneysel veri esas alınarak incelenmiştir. Hız değişimi etkisinde matematiksel model hesaplamaları ile elde edilen kritik çap değerleri ve değişim oranları ile deneysel çalışmalarda verilen kritik çap değerleri ve değişim oranları kıyaslanmıştır. Sonuçta kritik çapın hızın karekökünden daha hızlı değişim gösterdiği görülmüştür. Buna göre kritik çap tahmininde hızın etkisi açısından hıza bağlı ilave terimler içeren veya sürtünme kayıplarındaki değişimi dikkate alan modellerin daha duyarlı olduğu sonucuna varılmıştır.
