摘　　要：为实现宽流量范围下气液两相流的高效分离,基于螺旋线理论设计出了一种新型蜗壳式多通道旋流分离器,并对其结构进行了优化设计。采用数值模拟方法将其与传统单入口气液旋流分离器进行性能对比,结果表明,新型蜗壳式多通道旋流分离器能有效解决单个入口所引起的空气核偏心现象及振荡问题,分离器内流场在不同入口含气率条件下均具有显著的轴对称特点,稳定性也更高,溢流带液量明显下降。虽然整体压损更大,但能够有效抑制二次流的产生,且在入口含气率越高时抑制效果越明显。In order to achieve the efficient separation of gas-liquid two-phase flow in a wide flow range,a new volute type multi-channel cyclone separator was designed based on the spiral theory,and its structure was optimized.A numerical simulation method was used to compare its performance with that of a traditional single-inlet gas-liquid cyclone separator.The results showed that the new volute type multi-channel cyclone separator can effectively solve the problem of air core eccentricity and oscillation caused by a single inlet.The flow field in the separator has distinct axial symmetry and higher stability under different inlet gas content conditions,and the amount of liquid in the overflow zone decreases significantly.Although the overall pressure loss is greater,the secondary flow can be effectively inhibited,and the suppression effect is more pronounced when the inlet gas content is higher.
