Solving Particle-Laden Fluid Flows with a Continuous Approach

The multi-scale method called Pseudo-Direct Numerical Simulation (P-DNS) was previously extended by the authors to study the phenomenon of turbulence modulation in a particle-laden flows. However, in that article, the particles in both, the fine scale and the coarse scale, were treated in a discrete way moving in a Lagrangian reference frame within the fluid. In this presentation, the same P-DNS method will be used to simulate the presence of particles as a continuum function that moves within the fluid. In this way, the need to represent each of the particles that move in the fluid is avoided.
