Course Description

  This course is designed to provide students with a strong background on 
fundamental fluid mechanics the necessary understanding of the dynamics
of multiphase flow to carry out research in their area of interest. Particular
emphasis will be placed on bubble and particle dynamics, including
sediment transport, cavitation, atomization and other environmental and
industrial processes. 
Although we will cover both Eulerian-Eulerian (two fluid) models and
Eulerian-Lagragian (discrete particles) models, most of the material
concentrates on the study of a discrete phase (particles, droplets or
bubbles) in a continuous phase. 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.

Lecture Notes
