INVESTIGATION OF THE EFFECT OF NUMBER OF GUIDE VANES ON SEPARATION EFFICIENCY AND PRESSURE DROPS IN THE AXIAL FLOW CYCLONES
Abstract
In this study, the effect of the number of guide vanes on separation efficiency and pressure drops in the axial flow cyclones was investigated using the Computational Fluid Dynamics (HAD). Axial flow cyclones were compared with the tangential and reverse flow cyclone separators, which provide high particle collection efficiency and pressure drop. Axial flow cyclones were considered in this study by taking into account the similar studies in the literature. In the study, guide vane numbers ranging from 2 to 10 were examined for four different situations The particle separation efficiency and pressure drops in the proposed axial flow cyclone were computed by using numerical model. The HAD results of the axial flow cyclone are, for the four cases studied, the situation where the fixed vane angle and vane rotations are inversely proportional to the number of vanes, compared to the other three cases, it was observed that the performance increased as the number of vanes increased.

EKSENEL AKIŞLI SİKLONLARDA KANAT SAYISININ AYIRMA VERİMİ VE BASINÇ KAYIPLARINA OLAN ETKİSİNİN ARAŞTIRILMASI
Abstract
Bu çalışmada, eksenel akışlı siklonlarda kanat sayısının ayırma verimliliği ve basınç kayıpları üzerindeki etkisi Hesaplamalı Akışkanlar Dinamiği (HAD) kullanılarak incelenmiştir. Eksenel akışlı siklonlar, yüksek partikül ayırma verimliliği ve basınç düşüşü sağlayan teğetsel ve ters akışlı siklon ayırıcılar ile karşılaştırılmıştır. Literatürdeki benzer çalışmalar dikkate alınarak bu çalışmada eksenel akışlı siklonlar ele alınmıştır. Çalışmada 2 ile 10 arasında değişen kılavuz kanat sayıları dört farklı durum için incelenmiştir. Önerilen eksenel akış siklonundaki partikül ayırma verimi ve basınç kayıpları sayısal model kullanılarak hesaplanmıştır. İncelenen dört durum için, eksenel akışlı siklonun HAD sonuçları, sabit kanat açısı ve kanat dönüşünün kanat sayısı ile ters orantılı olduğu durumun diğer üç duruma kıyasla, kanat sayısı arttıkça performansın arttığı görülmüştür.
