Type of article: Article

Summary

THE MOVEMENT OF SMALL PARTICLES DISTRIBUTED UNIFORMLY IN AN UNSTEADY FLOW IN A SQUARE CHAMBER HAVING AN INLET AND AN OUTLET WAS SIMULATED. PARTICLES WERE CLASSIFIED INTO 3 TYPES ACCORDING TO THEIR FINAL STATE: EXHAUST TYPE, CIRCULATION TYPE AND ADHESION TYPE. THE INFLUENCE ON MOVEMENT OF THE INITIAL POSITION OF A PARTICLE, THE REYNOLDS NUMBER, AND THE DIMENSION RATIO CHARACTERIZING WHETHER A PARTICLE IS COARSE OR FINE, WERE EXAMINED. MOVEMENTS ARE LARGELY AFFECTED BY FLUID FLOW AND THE DIMENSION RATIO. THE PARTICLE MOVEMENT OR THE CLEANLINESS OF A ROOM CAN BE CONTROLLED BY CONTROLLING THE FLOW FIELD.
