Simulation and experimental validation of dust deposition near ventilation outlets

摘要

Dust deposition near ventilation outlets mainly consists of organic particles that (stem from the room. The particles are shaped elliptically and aerodynamically behave like spheres with a diameter of 1 to 30μm. Numerical simulation of the airflow combined with experiments allow a scrutiny of the process and facilitate the search for countermeasures. It shows that particle deposition is mainly affected by turbulence.
