Analysis of Numerical Modelling of Turbulence in a Conical Reverse‐flow Cyclone

Abstract: This paper aims to analyse the problem of numerical modelling of the airflow in a conical reverse‐flow (CRF) cyclone with tangential inlet (equipment for separation of solid particles from gaseous fluid flow). A review of experimental and theoretical papers that describe cyclones with very complex swirling flow is performed. Three‐dimensional transport differential equations for incompressible turbulent flow inside a cyclone are solved numerically using finite volume‐based turbulence models, namely, the Standa… Show more

“…Therefore, the evaluation of particle behavior is a crucial aspect. In order to gain higher air cleaning effectiveness, the assessment of pollutant behavior is important for designing air cleaning devices (Hoffmann 2000;Baltrėnas and Zagorskis 2010;Vaitiekūnas and Jak s stonienė 2010;Pushnov and Berengarten 2011;Baltrėnas et al 2012;Luca and Ioan 2012). Microparticles in the above-introduced equipment most frequently precipitate under the influence of sedimentation processes taking place in the multichannel cyclone and stick to the partition wall of the device.…”

“…Highly efficient cyclones and filters are used to reduce dustiness in industry [17]. Cyclone's two most important working parameters, collection efficiency and pressure drop, largely depend on the concentration of dispersed PM [6,23].…”

“…Patterson and Munz [18] studied the effect of PM concentration (of up to 235.2 g/m), fluid temperature (from 300 K to 2000 K) and gas inlet velocity (from 3 m/s to 42 m/s) on cyclone's collection efficiency and determined that an increase in PM concentration had improved the efficiency of collection, in particular at a high temperature [8,23].…”
