Impacts of Urban Layouts and Open Space on Urban Ventilation Evaluated by Concentration Decay Method

Previous researchers calculated air change rate per hour (ACH) in the urban canopy layers (UCL) by integrating the normal component of air mean velocity (convection) and fluctuation velocity (turbulent diffusions) across UCL boundaries. However they are usually greater than the actual ACH induced by...
