Impedance Sensors for Fast Multiphase Flow Measurement and Imaging
Multiphase flow denotes the simultaneous flow of two or more physically distinct and immiscible substances and it can be widely found in several engineering applications, for instance, power generation, chemical engineering and crude oil extraction and processing. In many of those applications, …

Early Stages of the Aluminothermic Process: Insights into Separation and Mould Filling
The aluminothermic (AT) process utilises a self-propagating high-temperature synthesis (SHS) type reaction for producing primarily thermite steel and alumina slag at high temperatures during the welding of rails. In this work, an investigation on the early stages of the aluminothermic process, the …

Dynamisches Mehrphasenmodell mit hypoplastischer Materialformulierung der Feststoffphase
The numerical simulation of heterogeneous materials with solid and pore filling fluid phases becomes more and more important in different areas of engineering practice due to the availability of high performance computers. The classical application area of multiphase models is the investigation of …

Numerical methods for three-dimensional incompressible two-phase flow problems
In this thesis a numerical approach for the simulation of three-dimensional incompressible two-phase flows is presented. It is based on a level set method for capturing the interface. The mathematical model consists of the incompressible Navier-Stokes equations and an advection equation for the …
