PHYSICAL MATHEMATICS SEMINAR

TOPIC:		SIMULATION OF FLOWS WITH FREE SURFACES:
		BUBBLE DYNAMICS, CAVITATION AND SPLASHING

SPEAKER:	DR. STEPHANE ZALESKI

ABSTRACT:

Numerical methods for the solutions of Navier-Stokes equations with
interfaces between phases and free surfaces will be discussed. The VOF
methods conserve volume exactly and are robust, while the marker chain
methods allow greater accuracy and stability.

These methods offer a unique approach to problems such as bubble
deformation in cavitating flows and in the regime of single bubble
sonoluminescence. The problem of crown formation for splashing droplets
will also be discussed.
