An Unsteady Transport Model for Gaseous Pollutants in Partitioned Buildings

Project Details


Natural ventilation is widely used to improve the indoor air quality and to save energy from mechanicalventilation in residential buildings. However, hazardous air pollutants (HAPs), such as CO (carbonmonoxide), NOx, SOx, and VOCs, could transport in and out of buildings through building openings. Thisstudy plans to use wind tunnel experiments and an unsteady model to investigate the transport process ofgaseous pollutants in partitioned buildings. The transport rates of gaseous pollutant inside a scale model willbe measured by the tracer decay technique, and the internal and external pressures will be measured by amulti-channel pressure scanner. The effects of external wind speed, wind direction and opening area on thetransport rate will be systemically investigated in a series of wind tunnel experiments. The experimentalresults will be used to develop an unsteady transport model for gaseous pollutants in partitioned buildings.Then the transport model can be applied to evaluate the influences of external wind speed and openingstrategy on the transient concentration of gaseous pollutants in buildings.
