My recent experiments have focused on the dynamics of free-surface flows, such as:

Drop impacts onto solid and liquid surfaces.    These phenomena are of importance in spray coating and spray cooling.

Entrapment of air under an impacting drop.       Of relevance in gas transport between Ocean and Atmosphere and in many chemical processes.

Coating flows inside a rotating cylinder.   Relevant to roto-molding and general film-coating processes.

This study looks at flow instabilities inside a partially-filled horizontally rotating cylinder.
