Abstract: A series of orthographic experiments were designed to optimize and design the cyclone separator geometry by adopting the CFD-DPM (computational fluid dynamics-discrete particle model) and the response surface method. The effect of seven cyclone geometrical parameters and their interactions on the performance were investigated. The results show that the most significant geometrical parameter is the vortex finder diameter. Other factors of the inlet width, inlet height, total cyclone height, and vortex finder length have significant effects on the cyclone performance. In addition, there are strong interactions between the effect of the inlet dimensions and the vortex finder diameter on the pressure drop. There are strong interactions between the effect of the vortex finder length and total cyclone height, inlet width and vortex finder diameter, inlet width and total cyclone height, vortex finder diameter and total cyclone height on the separation efficiency. Finally, a new set of geometrical ratios are obtained to achieve minimum pressure drop maximum separation efficiency by optimization of the response surface of each index.
