I am a student, and study hydrodynamics and introduction of particulate matter by myself.My main research field is CFD-DEM, as well as the contamination problem under multi-field coupling. In the Eulerian-Eulerian models, the particles are treated as a continuous phase and conservation equations are solved for the particulate phase. This method is suitable for large particle concentrations, where two-way coupling between the uid and the particulate phases as well as particle-particle collisions are important. On the other hand, in the Eulerian-Lagrangian approach, the Eulerian continuum equations are solved for the uid phase, while Newton's equations for motion are solved for the particulate phase in order to determine the trajectories of the particles (or groups of particles).i am interested in the aerodynamics ,and hope to be able to accomplish something in this regard.
