1. Phase Doppler Anemometry in Unsteady Two-Phase Flow: A Novel Post-Processing Data Algorithm
Sammanfattning : This thesis presents a novel method to estimate particle fluctuations in unsteady two-phase flow using phase Doppler anemometry (PDA). A comprehensive derivation and asuccessful validation of a PDA data post-processing algorithm are given. LÄS MER
2. Volumetric MRI measurements of velocity and flow - Accuracy, visualisation and technical improvements
Sammanfattning : In the last two decades, phase-contrast magnetic resonance imaging (PC-MRI) has evolved from two-dimensional velocity and flow measurements to volumetric, time-resolved depictions of velocity fields (4D PC). The acquisition of time-resolved velocity fields allows flow visualisations that might provide better understanding of the dynamics of the cardiac system. LÄS MER
3. Some two-phase flow and boiling heat transfer characteristics in small diameter tubes
Sammanfattning : .... LÄS MER
4. Phase-changing flows: numerical methods and fully resolved simulations
Sammanfattning : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.

5. Mass Conserving Simulations of Two Phase Flow
Sammanfattning : Consider a mixture of two immiscible, incompressible fluids e.g. oil and water. Since the fluids do not mix, an interface between the two fluids will form and move in time. LÄS MER
