Lattice Boltzmann methods for nanotechnology application
Description
The production of nanoscaled particles with specific
characeristics is crucial for many applications. To improve
understanding of the properties of such aggregates in fluid
suspensions we use the Lattice Boltzmann method. This
allows us to determine basic parameters for single
aggregates, like the drag force. More complex problems like
the breaking in shear flow or further agglomeration of the
molecules can also be simulated this way.
Our approach requires the incorporation of boundary
conditions for moving obstacles into the fluid simulation
to calculate the bidirectional influences of fluid and
obstacles. Furthermore the behaviour of the aggregates
themselves can be computed using a rigid body physics
simulation. We are currently working on including the
effects of long range potentials into the simulation. To
compute segregation processes with many aggregates and
larger regions of fluid, the implementation will be
parallelized to run on large clusters or supercomputers.
