Course Description

This course is designed to provide students with a background on fundamental fluid mechanics and the fundamental understanding of the dynamics of multiphase flow. It will cover Eulerian-Eulerian (two-fluid) models, Eulerian-Lagrangian (discrete particles) models, and discrete phase (particles, droplets or bubbles) in a continuous phase. Emphasis will be placed on bubble dynamics, including cavitation and atomization, with particular attention on numerical methods for interface tracking. Topics will include Basset-Boussinesq-Oseen equation of motion for a particle in a non-uniform flow, particle interactions with turbulence, inertial clustering, cavitation and bubble dynamics, droplet breakup, collisions and coalescence, and surface tension effects. Part of the course will be devoted on the presentation of state-of-the-art application on engine injection, process engineering, and reacting particles.
