The effect of the cone tip-diameter on the flow field and performance of cyclone separator was investigated computationally and via mathematical models. Three cyclones with different cone tip diameters were studied using large eddy simulation (LES). The cyclone flow field pattern has been simulated and analyzed with the aid of velocity components and static pressure contour plots. In addition the cyclone collection efficiency based on one-way discrete phase modeling has been investigated. The results obtained demonstrate that LES is a suitable approach for modeling the effect of cyclone dimensions on the flow field and performance. The cone tip-diameter has an insignificant effect on the collection efficiency (the cut-off diameter) and the pressure drop. The simulation results agree well with the published experimental results and the mathematical models trend.
► Three cyclone separators with different cone-tip diameters (Bc) have been investigated with LES. ► Grid independency has been tested using grid convergence index (GCI). ► Deep analysis for the effect of the cone-tip diameter on the cyclone performance and flow pattern. ► The cone-tip diameter has an insignificant effect on the flow pattern and performance. ► Decreasing Bc slightly increases the pressure drop and slightly decreases the cut-off diameter.
