Abstract : Controlling air pollution is important for healthy well-being of humans and nature as a whole. The presence of particulate matter in air is a serious matter of concern as it causes several health hazards. One of the most cost effective and efficient methods to separate particulate matter is by using cyclone separator. Cyclone separator is a device without any moving parts having tangential inlet velocity of gas stream transformed into a compact vortex or spiral flow downward between walls of gas discharge outlet and body of cyclone. The centrifugal force resulted by vortex or spiral creation leads to coarse particulate separation of particulate matter (24–30 μm) from the polluted air. This paper presents the design of a 2D-2D cyclone separator using Lapple mathematical model. Tangential inlet velocity and barrel diameter of cyclone separator are some of the important factors which collection efficiency depends on. Optimum barrel diameter and inlet velocity for highest collection efficiency were found by numerical analysis using Lapple model, in which former parameter was made fixed and latter changed and vice versa. The iteration was further carried out on four particles of different densities like manure dust, Arizona test dust, fly ash, and micro-alumina. Collection efficiencies of cyclone separator were determined for the selected particles above mentioned. It was observed that the collection efficiency reached a maximum after a size range (24–40 μm) of particles. The theoretical results obtained were verified with the results obtained in CFD.
