Enhancing Gas Cyclone Performance with Exit Diffusers
Year: 2025
Type: article
Abstract: This study evaluates seven cyclone designs to enhance pressure drop and collection efficiency (CE), using the conventional cyclone as a baseline. While the conventional design is efficient in particle collection, it experiences significant energy losses due to high values of pressure drops. This study introduces exit diffusers with various configurations—A, B, C, D, E, and F—to improve cyclone performance. Computational Fluid Dynamics (CFD) simulations were used to analyse the pressure drop, tangential velocity, and static pressure at different levels of each cyclone. The findings reveal that cyclone D achieves a 41.1% reduction in pressure drop but at the cost of a 21.3% decrease in the CE. Cyclone C presents a balanced option, with a 28.0% reduction in pressure drop and only a 7.9% decrease in CE, making it suitable for industrial applications. Cyclone F shows a 39.6% improvement in pressure drop, though it results in a 19.7% reduction in CE.
