Turbulence intensity plays a critical role in determining the particle separation efficiency within gas-solid cyclones. While moderate turbulence enhances particle mixing and promotes effective collection, excessive turbulence can induce particle re-entrainment, thereby diminishing system performance. Parameters such as inlet velocity, particle size, and cyclone geometry are key contributors to the intensity of turbulence. Computational Fluid Dynamics (CFD) is extensively employed for optimizing cyclone design. This study investigates the variations in turbulence intensity across different cyclone configurations equipped with spiral guide fins. The findings reveal that cyclones incorporating 3.5 mm and 4.2 mm fins exhibit elevated turbulence levels, which are associated with increased energy dissipation and pressure drop. The maximum turbulence intensity is identified in the cyclone featuring a 2.8 mm fin and a pitch length of 1.25D. Interestingly, the presence of spiral fins leads to increased turbulence only under specific conditions, likely due to the greater number of fin turns, which amplify flow velocity and induce higher levels of disturbance.
