Abstract

This work examines the influence of the particle shape on heavy particle dispersion in a neutrally stratified atmosphere. The particle trajectories are analysed in terms of particle landing positions downwind from the source. For this purpose an already existing Lagrangian model [1] has been modified to deal with non-spherical particles. The particle trajectories are calculated by numerically solving Newton's equations of motion, while the wind velocity is modelled by means of a Markov chain scheme. The simulation runs have been performed for lOOp, particles of different non-sphericity released from the elevated source. The results indicate that the shape of the particle is a very important parameter in determining the deposition curves. In general with increasing non
