The performance of a novel cyclone separator with a cone made of porous sintered metal was compared with that of a conventional design with a cone made of acrylic resin. Controlled injection of clean air through the porous cone is proposed as a new method to control the cut size and reduce powder deposition on the cone.In the experiments, when clean air was not injected through the porous cone, the cut size and the amount of powder deposited on the porous cone were greater than for the acrylic resin cone. However, the introduction of adequate clean air through the porous cone simultaneously reduced the cut size and the powder deposition to less than those with the conventional cone. The revised horizontal-flow model revealed that this occurred because the injected clean air enhanced the tangential velocity of the fluid near the cone surface by reducing the surface's apparent friction factor.

将具有由多孔烧结金属制成的锥体的新型旋风分离器的性能与具有由丙烯酸树脂制成的锥体的传统设计的性能进行比较。提出了通过多孔锥体控制注入清洁空气作为控制切割尺寸和减少锥体上粉末沉积的新方法。在实验中，当不通过多孔锥体注入清洁空气时，切割尺寸和粉末量沉积在多孔锥体上的粉末比丙烯酸树脂锥体上沉积的粉末多。然而，通过多孔锥体引入足够的清洁空气同时减少了切割尺寸和粉末沉积，使其小于传统锥体的尺寸。修正后的水平流模型表明，这种情况的发生是因为注入的清洁空气通过降低表面的表观摩擦系数而增强了锥体表面附近流体的切向速度。
