Some Studies on Effect of Particle Source Locations on Ventilation Effectiveness in Displacement Ventilated Room
Keywords:
Computational Fluid Dynamics, Particle SizeAbstract
Ventilation effectiveness is the ability of the ventilation system to fulfill the design goals such as provision of fresh, healthy air to the occupants, dilution and removal of contaminants from the occupied zone of the mechanically ventilated room. Computational fluid dynamics (CFD) has become an efficient tool for determining the airflow, heat transfer and contaminant transport in the enclosed room environments and for wide range of other HVAC&R applications.However, these CFD studies remain less relevant and useful unless and until these are backed up by proper experimental studies. Factors such as outdoor air quality, airflow rate, air supply method, moisture content, thermal environment and contaminant source location have greater impact on ventilation effectiveness.
