Modelling of pollutant dispersion from sources in complex turbulent flows

Objetivo



The development of an unsteadyNavier-Stokes computer code is proposed for the study of pollutant dispersion in complex flows. The velocity-vorticity formulation of the equations will be considered and a method which uses vortex particles in an unstructured finite element mesh will be used. Turbulence will be modelled using a one equation turbulent transport model. Pollutant particles will be released from point or line sources and their trajectories will be computed as a function of time.
The resulting flow field will be used as an input to a Lagrangian statistics model for the calculation of the pollutant concentration. The flow around models of structures in the atmospheric boundary layer (buildings, hills etc.) will be computed and the pollutant dispersion will be studied. Comparison with existing experimental data will be performed in order to validate the computational model.
