Abstract A cyclone is widely used in the industrial world for the particle separation process. Many geometrical and operational parameters affect the cyclone separator performance. The main aim of the present study is to investigate the effect of the position of the vortex limiter and the insertion of the metal rod on the heat transfer, flow field, and cyclone performance using the computational fluid dynamics (CFD) method. Vortex limiter position varies among 160 mm, 320 mm, and 480 mm. In this work, the Reynolds stress model (RSM) is used to simulate the flow, and the Eulerian-Lagrangian approach is employed to predict the movement of particles in the cyclone. Simulation results show that the insertion of a metal rod increases the heat rate and collection efficiency by about 22% and 13%, respectively. The results also confirm that the vortex limiter position is proven to affect the performance of cyclone significantly.

涡流限制器位置和金属棒插入对旋风分离器流场、热率和性能的影响

摘要 旋风分离器在工业界广泛用于颗粒分离过程。许多几何和操作参数会影响旋风分离器的性能。本研究的主要目的是使用计算流体动力学 (CFD) 方法研究涡流限制器的位置和金属棒的插入对传热、流场和旋风性能的影响。涡流限制器位置在 160 毫米、320 毫米和 480 毫米之间变化。在这项工作中，雷诺应力模型（RSM）用于模拟流动，并采用欧拉-拉格朗日方法来预测气旋中粒子的运动。仿真结果表明，金属棒的插入使热率和收集效率分别提高了约 22% 和 13%。
