Özet:The aim of this study is design and experimental investigation performance of a mini cyclone separator with the virtual body and to carry out and investigate the cyclone efficiency, cut-off diameter, tangential velocity profiles and pressure losses under the influence and effect of different cyclone length, roughness and inlet velocity of a cyclone separator. The governing equations for this flow were solved by using Fluent CFD code First and Second numerical analyses were run to verify numerical solution and were compared with experimental results. Tangential velocity profiles, cyclone efficiency, cut-off diameter, and pressure drops were calculated by defining the height of cyclone from 10 cm to 20 cm, inlet velocity 18.5, 27.8, 37.04, 46.3, 55.5 and 64.8 m/ s, 0.004131 Kg/s has been added as mass flow rate. Analyses of results and CFD predictions have shown that an increase in cyclone length lead to the decrease of cyclone efficiency and pressure drop in addition to tangential velocity decreases with increasing cyclone height, so that should be responsible for the lower separation efficiency observed in long cyclones. The higher tangential velocity will not give rise to the higher cyclone efficiency, in order to explain that the cyclone efficiency decreases when the cyclone height is increased, less gas will migrate down to the bottom section where it can be accelerated due to the decreased cross-section area, in contract CFD predictions showed an increase in cyclone inlet velocity and particles diameter lead to increase of cyclone efficiency, pressure drop and Tangential velocity increasing with cyclone inlet velocity increase. Experiments have been carried out on a cyclone with a 10cm length and 20 cm, the effect of changing cyclone length were studied. The results of the experimental measurements are compared with data obtained from numerical solution. The given results show qualitative agreement with each other.
