摘要：
This paper presents numerical simulations of tracer gas experiments performed at Forte Maillot in Paris. The Reynolds-averaged Navier-Stokes equations, combined with the dual-time scale k-epsilon turbulence model of Chen and Kim, are solved using the finite-volume code PHOENICS. Good agreement with in situ measurements is obtained. The effects of turbulence modelling, numerical diffusion, boundary conditions, turbulence and drag forces generated by traffic are investigated.
