DESIGN AND CFD ANALYSIS OF SINGLE AND SYMMETRICAL INLET CYCLONE DUST SEPARATOR

Aeronautical Engineering

We are using cyclone dust separators for quite a century. Gas-solid cyclone separators are the most frequently used equipment in industries. To enhance the performance of cyclone dust separators, many Computational Fluid Dynamics studies conducted for its wide variety of applications in industries. Computational Fluid Dynamics is a conventional method to forecast the flow and collection efficiency of a cyclone. Primarily three models were used in cyclone simulation K-Epsilon Model, Reynolds Stress Turbulence Model, and Algebraic Stress Model. The K-epsilon turbulence model is the foremost crucial model utilized in computational fluid dynamics analysis to simulate turbulent kinetic and dissipation conditions. Pressure drop in the cyclone separator is one of the most significant functions to be kept in mind while designing the cyclone system. For further improvement in cyclone dust separator, a comparison of the pressure drop in a single and symmetrical tangential input cyclone separator perform theoretically and computational fluid dynamics analysis using the Reynolds stress turbulence model. The result showed that the pressure drop in the symmetric inlet cyclone separator exceeds the single inlet cyclone separator. I also performed the Computational Fluid Dynamics analysis to calculate the efficiency of a cyclone separator with a dust collector using the K-Epsilon Turbulence Model. So far, we all know that the pressure drop in a cyclone separator is directly associated with the tangential velocity of the cyclone separator, which must increase to extend the efficiency of the cyclone. Cyclone efficiency will generally increase with increment in particle size or density, tangential velocity, cyclone body length, and smoothness of the inner wall of the cyclone.
