The interaction of gas bubbles and the surrounding liquid in bubbly flows is a complex
hydrodynamic phenomenon. Precise measurements of the liquid velocity are mandatory to …

The lift force is known to strongly influence the lateral bubble distribution in bubbly flows and
is therefore an important force that has to be modeled in corresponding CFD simulations …

In this research, visualization of particles is achieved by leveraging optical activity that is
inherent in the helical and crystalline structure of many substances. Optically active particles …

Particle shadow velocimetry (PSV) is an optical, LED-based flow diagnostic technique that
images a backlit flow field and uses inverted images to quantify the velocity. The planar, two …

This thesis analyzes a high Reynolds number, axisymmetric, turbulent pipe flow for the
purpose of developing a turbulence model that describes the mean velocity and two-point …

In this dissertation, the method of planar particle shadow velocimetry (PSV) is studied,
compared to particle image velocimetry (PIV), and advanced into two new forms not …
