The large-eddy simulation (LES) and Reynolds-averaged Navier–Stokes (RANS)
methodologies are used to simulate the air flow inside the container's array geometry of the
Mock Urban Setting Test (MUST) field experiment. Both tools are assessed and compared in
a configuration for which the incident wind direction is perpendicular to the front array. The
assessment is carried out against available wind-tunnel data. Effects of including small
geometrical irregularities present in the experiments are analysed by considering LES and …

Large-eddy simulations (LES) and Reynolds-averaged Navier–Stokes (RANS)
computations of pollutant dispersion are reported for the Mock Urban Setting Test (MUST)
field experiment flow. In particular we address the effects of incident wind angle deviation on
the mean velocity and on the mean concentration fields. Both computational fluid dynamical
methods are assessed by comparing the simulation results with experimental field data. The
comparative analysis proposes to relate the plume deflection with the flow channelling …
