“…In their theories they considered more parameters such as surface roughness, area of distribution of particles, shape and size of particles, pressure losses and others. The efficiency of vortex separators depends on the regime, which is also influenced, apart from the already mentioned parameters, by inlet velocity, temperature and viscosity, which are introduced in the work of Avci and Karagoz (2003). This work investigated the cyclone flow patterns introducing different shapes and diameters of exit tube simulated at diverse flow rates.…”

-The paper shows the analysis of the effect of introduction of an exit tube into the cylindrical part of a cyclone on the flow velocity, pressure losses and, above all, the separation efficiency. We made measurements and carried out CFD simulations for three levels of the exit tube introduction. The ratios of the depth of the exit tube introduction to the cyclone diameter (Hp/D) were 0.4, 0.475 and 0.89 at three velocity settings of 8 m.s -1 , 13 m.s -1 and 15 m.s -1 . The Reynolds Stress Model (RSM), which was compatible with the experimental results, was used for numerical solutions. The efficiency of cyclone separation was explored on a sample of oak sawdust. The efficiency of cyclone separation increased with the geometric size of the particles, the inlet velocity and a deeper introduction of the exit tube.

“…The aim of this study is to extent the model developed by Avci and Karagoz (2003), which is successful in estimating the collection efficiency, to the prediction of pressure drop depending on the geometrical dimensions and operating conditions in a tangential inlet cyclone. Contrary to the other models, the proposed model includes the effects of surface roughness, Reynolds number, which contains temperature effects implicitly, and almost all of the parameters (such as inlet and outlet geometries, shortcut flow, cone shape, etc.…”

“…The collection efficiency and pressure drop resulting from this model were compared with the cyclone/multi-cyclone of different models, for example, Leith and Licth model (Coker 1993;Leith & Licht 1996;Licht & Koch 1977), Barth model (Bohnet et al 1997), Mothes model (Mothes & Löffler 1988), Lorenz model (Lorenz 1994, CFC (Wanga et al 2010), DIII model (Wang et al 1990), Ideal-laminar cyclonic flow model (Benitez 1992), turbulent cyclonic flow model (Benitez 1992), not ribbed-CFD, rib pitch to cyclone diameter ratio (P/D)=1.5-CFD, P/D=1-CFD Ideal (Farahani et al 2011) and Karagoz model (Avci & Karagoz 2003). The data of collection efficiency and pressure drop were taken from the descriptions of the individual model found in literatures.…”
