Abstract [en]

We have developed a fully parallel fortran/MPI code for tracking particles in homogeneous turbulent flows. The fluid is discretized in a uniform Eulerian grid while the particles are evolved via a Lagrangian tracking framework. The code is pseudo-spectral and employs the libraries FFTw, time integration has a third or fourth-order accuracy. The carrier phase can transport several equations for active/passive scalars that can act like a source of mass/energy transfer to the particles. We were able to simulate a fully-turbulent flow in an Eulerian grid of about 10(10) points and to track in a Lagrangian framework at least 10(9) point particles. The code is fully modular, can be easily extended or modified and available upon request.
