Design Data for Cyclones

Abstract

For many years efforts have been made to describe the complex process of particle separation in cyclones, and a multitude of separation models have been set up. A comparison of such separation models fails because insufficient usable test results are available and systematic and precise investigations are missing. It is important for the design of cyclones to rate their separation properties by means of the fractional collection efficiency. On account of the known measuring problems, the data supply of

Numerical prediction of short-cut flows in gas-solid reverse flow cyclone separators

“…Optimization of cyclone performance by increasing cyclone separator collection efficiency and reducing the pressure drop was mainly derived from experiments rather than theoretical studies because the fluid motion in cyclones are complicated, including highly swirling turbulent characteristics and restrictions in the usage of empirical models [8,9,[11][12][13][14][15][16].…”

Usability of cyclone separators as air filters in vehicles

“…Earlier experimental works were performed mainly for development of different type of cyclones (Lapple, 1951;Kim and Lee, 1990;Köning et al, 1991;Upton et al, 1994) and investigation of their performances (Moore and Mcfarland, 1993;Kenny and Gussman, 1995;Ozkoca, 2001;Avci and Karagoz, 2003;Karagoz and Avci, 2005). Simultaneously, theoretical analyses of the flow inside cyclones and various mathematical models have also been developed (Shepherd and Lapple, 1939;Stairmand, 1951;Alexander, 1949;Barth and Leineweber, 1964;Zhu and Lee, 1999).…”
