| Outline of Final Research Achievements |
The purpose of this paper is to report the useful design guidelines gained by conducting an investigation on the relationship between the flow conditions inside a cyclone and the dust collection and particle classification performance of the cyclone. This task carried out by conducting dust collection and particle classification experiments, implementing Fluid analyses using OpenFOAM and performing comparative analyses on the obtained results. The investigation aimed to gather basic data on the design of relatively large conical cyclones with large amounts of airflow containing dust, which used in actual dust collection plants. As a result, We elucidated the relationship between the flow conditions inside the conical cyclone when the size of the Classification area changed in a cyclone dust collector with and dust collection and particle classification performance.
