Eulerian modeling and simulation of small scale trajectory crossing and coalescence for moderate-Stokes-number spray flows

Résumé

A new Eulerian model is derived for polydisperse moderately-inertial sprays with coalescence: an Anisotropic Gaussian Velocity Closure conserves all the second order moments to render the spatial structure of the spray after Droplet Trajectory Crossing. Polydispersity is treated with a high order in size Multi-Fluid method where coalescence terms are directly computed from the velocity reconstructions. The approach is qualified on a crossing jet case against a semi-analytical solution and a Lagrangian Discrete Particle Simulation. The new model is ready for structured grid computations and promising for industrial computations, as it is flexible and of a high order in size and velocity.
