Drag Force Simulations of Particle Agglomerates with the Lattice-Boltzmann Method
Supervision:
Background:
In collaboration with the LFG Erlangen, the area of research for this
student 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 student thesis is the implementation of
a LBM that can accurately handle the curved boundaries
of particle agglomerates, and research the advantages of
these boundary conditions compared to the standard bounce-back
boundary conditions.
Task:
-
Implementation of accurate cuvred no-slip boundary conditions for LBM
-
Verification of the results with analytic results
-
evaluation of accuracy enhancements in comparison to
simple bounce-back coundary conditions
-
Realtime-visualization of the resulting flow field and body forces
