Design and Simulation of a High-Efficiency Cyclone Separator for Bioaerosol Collection

In this paper, we utilized the computational fluid dynamics (CFD) method to develop models A1 to A6 with varying column-cone ratios for the wet-wall cyclone sampler. The results indicate that within the pressure drop range of (869.7, 997.8) Pa, model A4 (with a column-cone ratio of 1:2) exhibits the highest collection efficiency, surpassing the lowest by 6.7%. In addition, we modeled B1-B3 with different cyclone heights and found that a cyclone height of 50 mm was most effective for balancing cyclone structures and improving collection efficiency.
