Abstract-
The flow of fluids in microgeometries is important in many
emerging technologies, including high-speed spin coating
in IC fabrication, coating over topographical features and
imperfections for ultra-thin lithographic applications,
and motion and manipulation of dispersed bubbles in MEMS
devices. These in turn lead to a class of fundamental
fluid mechanics problems in which interfaces and interfacial
forces play a major role. In this talk, I will discuss some
of recent theoretical and experimental work in these areas,
including instability of dynamic contact lines, flow over
topography, optimal leveling of films by Marangoni stresses,
and thermocapillary migration of bubbles in microchannels.
