Atomization and Sprays: The high velocity breakup of a liquid
mass into small droplets is called "atomization" and the aggregate of
all drops formed is referred to as a "spray". Atomization and sprays
are used in a wide variety of industries. Some specific
applications are spray combustion in furnaces and gas turbines, spray
drying and cooling, powdered metallurgy, spray-painting and coating,
inhalation therapy, and many others. Our objective is to develop
a better understanding of the mechanisms involved in the atomization
process. Our approach to this problem is both computational and
experimental. In the computational part we are working on free
surface flow modeling of the liquid-gas interfaces in turbulent flow
conditions. In the experimental part, we are using
the-state-of-the-art instrumentations to investigate the mechanism of
the droplet formation from various spray nozzles.

Experimental, numerical and analytical studies on flow-induced
vibrations in single-phase fluid flows. Applications include the
aerodynamic stability of overhead power conductors as well as the
stability of objects which are immersed in liquid or gas flows in
general.

paints, synovial fluids, polymer melts and shampoos. Fundamental
studies to understand the peculiar flow behaviour of these
fluids. Development of instrumentation to characterize their
fluid properties. Experimental and analytical research on fluid

Professor D. Steinman
Computational and experimental studies
are carried out on physiologically-relevant internal flows which
feature strong secondary flow features, unsteadiness, and transition to
turbulence. Emphasis is also placed on the visualization of CFD data in
meaningful manners.
Professor P.E. Sullivan
The investigation of coherent structures on mixing and transport in
turbulent flows, using both experimental and analytical
techniques. The experimental work uses rakes of multiple
hotwires, Laser Doppler Anemometry and Particle Image
Velocimetry. Application to an engine to determine the influence
of coherent structure on combustion, as well as a three-dimensional
wall jet to determine the influence of structure on the anisotropic
growth rate.
