Vorticity Measurements with Steady State Luminescence Anisotropy
While the measurement of velocity is well established in experimental fluid dynamics with various methods, a suitable one for vorticity is an ongoing challenge. The thesis aims to test a new concept for a vorticity measurement.
The steady state luminescence anisotropy depends on the rotation of the molecule in question. Higher rotation, e.g. caused by rotational Brownian motion or a fluid flow, alters the observed anisotropy in contrast to a rotation-free reference.
In consequence, the change in anisotropy can be related to the fluid rotation and temperature.
This thesis aims to investigate the suitability of steady state anisotropy change regarding the application to fluid rotation measurements, while it continues previous work of a Bachelor’s Thesis on this topic.
_Requirements:_
- Advanced knowledge of fluid dynamics
- Knowledge of flow visualization methods is advantageous
- Programming skills for test stand control and post-processing are advantageous (MATLAB, C/C++, Python)
- Knowledge of Optical Engineering is advantageous
