Abstract

We study fully developed three-dimensional turbulent flow over two-dimensional urban street canyons using the atmospheric LES model DALES. We simulate this case in a neutral environment and develop a steady state case of a heated urban canyon in a convective boundary layer. We find drag and heat transfer coefficients comparable to earlier studies.
