Gustav Amberg
This is the home page of Gustav Amberg, Professor of fluid mechanics at
the dept of Mechanics, KTH (Royal Inst of Tech), Stockholm.
During the period December 2004 – March 2013 I was the Dean of the
School of Engineering Sciences.
I am Vice-President
for Faculty Development and Gender Equity of KTH since 2008.
I have worked on modeling and numerical simulation of phenomena
involving phase change, fluid flows, heat and mass transfer, surface tension
effects, wetting, and other two-phase flows such as electrokinetic
separation. At present there is an increasing involvement in micro- fluidics
and fluid dynamics in microscopic dimensions. Here, various surface forces,
such as surface tension, electrical forces, etc, may
dominate. Recently we have analyzed dynamic wetting flows, droplet dynamics,
and droplet deposition, as well as electrokinetic
flows. There is also a long-standing collaboration with materials scientists,
where we have recently studied capillary effects in sintering, and martensitic
phase change.
Most of my recent research deals with convective heat and mass transfer
phenomena in materials processes of different kinds. It ranges from studying
more fundamental aspects of solidification and phase
change, to particular processes. In all of these problems convective heat
and mass transfer is a key element. I also work on thermocapillary
convection, fluid motions induced by surface tension variations over a free
surface. This is a common phenomenon in many materials processes, such as
crystal growth and welding. I am also involved in work on the growth of
individual dendritic crystals, using phase-field simulations. Recently I have
developed symbolic computation tools to generate
finite element code for general systems of partial differential equations,
which are used to simulate problems in the areas above. I have also done work
on rotating flows and two-phase flows.
