Abstract

Bu çalışmada, yüksek verimli Swift (HE) tipi siklonda giriş hızının toplama verimi ve basınç kayıplarına olan etkileri nümerik yöntemler kullanılarak ortaya koyulmuştur. 10 – 20 m/s aralığında altı farklı giriş hız değerleri için çalışmalar yapılmıştır. Yapılan bu çalışmada daha iyi sonuçlar elde etmek için küçük elemanlar ile gridleme işlemi gerçekleştirilmiştir. Reynolds Stress Model (RSM) türbülanslı akışın çözümlenmesi için kullanılmıştır. Çözümleme her bir giriş hızı için transient olarak 5 ms’lik 1000 adım ile 10000 iterasyon ile gerçekleştirilmiştir. Partiküllerin boyut dağılımlarını belirlemek için Rosin-Rammler metodu kullanılmıştır. Giriş hızının artışı teğetsel hızı artırdığı için partiküle etki eden santrifüj kuvveti artmıştır. Buda partiküllerin siklon duvarına doğru hareket etmesine ve toplama veriminin artmasına neden olmuştur. Giriş hızının artışı ile birlikte, dönen akışın artması dolayısıyla basınç kaybının çok fazla arttığı görülmektedir. Bu değişimin üstel olarak arttığı görülür. Giriş hızının artışıyla birlikte siklon duvarlarında oluşan basınçlar aşırı derecede artmıştır.

Abstract

In this paper, study is performed in order to demonstrate the effect of the inlet velocity on collection efficiency and pressure drop by using numerical methods. Numerical simulation is accomplished for six different inlet velocity at range of 10-20 m/s. Gridding was done with small elements to obtain better results. Turbulent flow is analyzed using Reynolds Stress Model (RSM). Set appropriate time steps to model the transient processes is 1000 for 5 ms with 10000 iterations. Rosin-Ramler size distribution method was used to calculate particle mass fraction. Centrifugal force increased because that for value of inlet velocity increases, the tangential velocity enhances. Based on this situation, it can be concluded that for the particles to move towards the cyclone wall and the collection efficiency increased. It is seen that with the increase in inlet velocity, the pressure drop increases greatly due to the increase in the rotating flow. It is expressed that this change increases as exponentially. It is also observed pressure on cyclone wall markedly increased with the increase inlet velocity.
