Dynamics of bubbles, drops and particles

This course provides the basis for understanding and modeling dispersed flows containing bubbles, drops or solid particles. Local dynamics are studied by writing the equation of the trajectory involving the forces of drag, history and added mass, in order to introduce the notions of terminal velocity, relaxation time and Stokes number.

Introduction: examples of industrial and environmental applications - Differences between bubbles, drops and solid particles
I. Solid particle dynamics: forces, drag laws, terminal velocity, relaxation time, Stokes number
II. Fluid particles (bubbles and drops): forces, drag laws, terminal velocity, relaxation time, Stokes number
III. Application examples
