CFD Applications

Our code has been ported from Fortran 95 to C++ and we will hope to put a nice GUI on it in 2007. 

Ultrahydrophobic Surfaces (Experiments by Prof Rothstein)

• These surfaces are characterized by hydrophobicity and roughness at the micron scale.  We optimize their properties in both laminar and turbulent flows using simulation.

Droplets (with Prof Schmidt)

• Droplets are controlled by the physics at their free-surface.  Level set methods and other alternatives smear the surface severely.  We use moving mesh methods with exact conservation properties.

• A key aspect of this work has been the implementation of surface tension. Since curvature is poorly defined on discrete surfaces - the correct discrete form for surface tension is necessary.  We are working on an implicit surface tension formulation to remove stability limitations.  

Turbulence (in conjunction with Prof de Bruyn Kops)

• Direct numerical simulations of turbulence for model testing and calibration.

• Large eddy simulations of turbulence.
