Analysis of Scalar Fluxes and Flow Within Modelled Intersection Depending on the Approach Flow Direction

Original language description

The influence of the approach flow direction on contaminant spreading and ventilation within an intersection in an idealised symmetrical urban area was investigated in this study. Advective horizontal and vertical scalar fluxes are computed from measureddata for five flow directions. The highest advective contaminant fluxes are measured in the bottom parts of street-canyons. The important role of the vertical turbulent scalar flux in ventilation of intersection is expected. Quadrant analysis of vertical flux of longitudinal momentum is used to determine a domination of sweep or ejection events above the intersection.
