The presence of bodies in a flow and the transport patterns of these bodies is a classic problem in fluid mechanics. Its analysis is required, whether it is for the transport of sediments along a coastline, the apparition of air bubbles in pipe flow, or aerosols released by fossil fuels. It is important to develop tools predicting the motion of those particles, as they can hinder the operation of many industrial structures and affect severely the environment.
Such developments have been done in Telemac-2D to allow different classes of bodies to be modelled. In this report the approach to model two type of particles in Telemac-2D are presented, and two new problems can now be modelled: algae blooms and oil spills.
