Aggregation and fragmentation dynamics of inertial particles in fluid flows
In dieser Arbeit wird numerisch die Dynamik von Inertialpartikeln untersucht, die durch Kollisionen aggregieren und unter bestimmten Bedingungen wieder fragmentieren. Unser Ziel ist vor allem ein besseres Verständnis natürlicher Phänomene wie zum Beispiel die Bildung von Tropfen in Wolken und …

Identifying dynamical boundaries and phase space transport using Lagrangian coherent structures
… which we study is of the nontrivial motion of inertial particles in a two-dimensional fluid flow. We use the method of FTLE to identify transport barriers that produce segregation of inertial particles by size. The second problem we study is the long range advective transport of plant pathogen …

Effects of ocean turbulence on the large-scale stratification and Small-Scale Particle Distributions
… correctly in ocean models. Part II: “Inertial Particles.” The motion of solid objects in the ocean such as plastic debris or freely floating oceanographic instruments may differ from that of the surrounding fluid due to differences in inertia. The details of the deviations of inertial …

Dynamically orthogonal field equations for stochastic fluid flows and particle dynamics
… for flow fields to study the motion of inertial particles in flows with uncertainties. Inertial or finite-size particles in fluid flows are commonly encountered in nature (e.g., contaminant dispersion in the ocean and atmosphere) as well as in technological applications (e.g., chemical …

Comparing Turbulent Dispersion Models for RANS Simulations of Particle-Laden Flows
The ingestion of sand-particles into turbomachinery decreases their longevity and perfor- mance and can even lead to failure. To address these problems, studying particle-laden flows is of high interest in the field. Due to their low computational cost, RANS simulations remain the preferred method …

Lagrangian dynamics of turbulence: Applications with 3D particle tracking velocimetry
… for a distinct characterization of the motion of particles. It is particularly useful in the understanding of dispersion, mixing, and transport phenomena. Due to the complexity and difficulty in quantifying Lagrangian properties, experimental studies on turbulence-driven phenomena in the …
