Lagrangian particle simulation of tracer dispersion in the lee of a schematic two-dimensional hill

Three-dimensional Lagrangian particle model, listed with tunnel experiment diffusion data, is used to compute the emitted tracer concentration in the base region of a two-dimensional hill. The results are used in a mass-consistent model to compute mean concentration fields and to interpolate the turbulence structure. The concentration fields depict topographical data on the flow structures in turbulence system.
