Lattice-Boltzmann Simulation of Flow around moving Particles
Supervision:
Background:
In collaboration with the LFG Erlangen, the area of research for this
master thesis is the simulation of agglomerates
of particles in fluids and gases. The goal of these simulations
is the computation of forces acting upon the agglomerates,
to simulate effects like the breaking up or further
agglomeration of the particles in the flow.
The fluid surrounding the particles will be simulated
with the Lattice-Boltzmann
method (LBM), due to the simplicity of
the base algorithm, and it's ability to handle complex
boundaries. It's suitability for the simulation of e.g.
particle suspensions was shown by Ladd et al., among others.
The target of this master thesis is the implementation of
a LBM with moving obstacles. This includes the hydrodynamic
interaction of the particles in the fluid, and the dynamics
of the particle agglomerates.
Task:
-
Implementation of a LBM simulation program with
multiple moving obstacle bodies
-
Calculation of forces acting upon a particle or an agglomerate of
particles in the fluid and the resulting movement
-
Incorporate enhanced boundary conditions
and fluid-body interaction
-
Result visualization for both flow and particle agglomerate/body movement
