Numerical simulation on the feasibility of the enhanced cyclone with split flow for applications in high temperature conditions and non-vertical installation conditions

The feasibility of the enhanced cyclone with split flow (ECSF) for applications in high temperature conditions and complex spaces was validated through numerical simulation, investigating the influence of operating temperature and tilt angle on ECSF performance and flow field. The Reynolds stress model and discrete phase model were employed to calculate the intricate rotating turbulence and trajectories of particle motion within the ECSF, respectively. The findings demonstrate that the separation capacity of ECSF diminishes with the increment of operating temperature. Moreover, the tilt angle has negligible influence on both performance and flow field characteristics of ECSF regardless of high or low feed flow rates or operating temperatures. This means that ECSF can be flexibly installed. This research provides valuable insights for promoting wider applications of ECSF. [Display omitted] •Separation efficiency and energy consumption of ECSF decrease with increasing operating temperature.•Suppression of local secondary flow by split flow is enhanced with increasing operating temperature.•Increase of operating temperature changes the triple-vortex structure of ECSF into a double-vortex structure.•ECSF can be installed flexibly as tilt angle has almost no effect on its performance and flow field.
