Beschreibung
Particle-laden electrokinetic flows comprise fluid flow, charged objects, and electric fields. The complex interplay of these effects makes predictions and calculations of electrokinetic systems difficult, especially for the large numbers of particles typically involved.
In this thesis, efficient algorithms for physically accurate, massively parallel multiphysics simulations of particle-laden electrokinetic flows on advanced high performance computers are presented.
For the coupled models and their implementation a systematic validation is carried out. The correctness of the overall algorithms for electrokinetic flows with charged or uncharged particles in the presence or absence of ions in the fluid is verified. Moreover, the tumbling motion of elongated particles in the viscous flow regime is examined.
To show the outstanding parallel performance of the algorithms for the simulation of millions of charged particles in fluid flow, their parallel scaling and numerical efficiency are analyzed on an advanced supercomputer.
