摘要: Abstract A two-dimensional, steady, k – e turbulence model was used to investigate the high Reynolds number skimming flow field of an urban street canyon. We describe critical canyon width-to-height ratios that distinguish a cascade vortex patterns form in Details are reported includes structure mean field, turbulent kinetic energy, length scale, eddy viscosity, and stress for three typical different aspect ratios, W / H , The consequences layering on vertical transport explored.
