摘要

In this research, we report a numerical and experimental study of the turbulent dispersion of a passive scalar released from a continuous ground-level point-source in a staggered array of 16 × 16 cubic obstacles. The numerical simulation of the flow and scalar fields was based on the Reynolds-averaged Navier-Stokes method and experimental measurements of the flow and dispersion were obtained in a boundary-layer water channel. Results of a detailed comparison between the water-channel experiment of flow and dispersion and model predictions of the mean flow, turbulence kinetic energy, mean concentration and concentration variance are presented.
