Droplet Dynamics Simulations of engines often use very
simplified models of droplet
break-up and collision. Detailed simulations can
help improve
these models. The following calculations were performed with a hp
finite
element
method developed by Dr. Helenbrook. The movie below shows a
drop breaking up due
to aerodynamic forces
The following is a
drop-drop collision simulation. There is a symmetry plane
along the
bottom of the domain so only 1
drop is shown. This simulation was performed using the
incompressible flow equations. If rarefied gas effects and
molecular interaction effects are not included, the drops always bounce
Mesh
Deformation
and Adaptation Mesh
deformation and adaptation algorithms enable accurate simulations
of problems in which the domain deforms or translates. The
following movie shows harbor traffic simulations in Galveston Bay
Texas. This adaptation algorithm was developed with
T.J. Baker (Princeton University) and the work was done in
collaboration with Oceanit Inc.
Coating Flow
Instabilities Coating
flows are important in many manufacturing processes. Usually
the development of instabilities in the flow is undesirable. The movie
shows an instability that develops in a single-layer coating flow. Coating flow
work was done in conjunction with S.P. Lin and W.Y. Jiang at Clarkson
and S.J. Weinstein at Eastman Kodak Co.
