This PhD-project involves a fundamental study of these surprising manifestions of turbulent flow, using advanced experimental techniques and direct numerical simulations using Europe's fastest supercomputer facilities. Turbulence simulations are based on modern spectral codes and Lattice Boltzmann algorithms are used for studies of droplet break-up in complex flows.
These algorithms are all available in our laboratory. The experiments use laser-induced phosphorescence and fast intensified cameras and machines where turbulence without a mean flow is created in air. Much of the experimental infrastructure is already present, which gives your research project a flying start.
The challenge of the experiments is to find image-based statistical quantities that can capture the de-mixing at the scale of the smallest turbulent vortices, and that can follow the fast initial stages of turbulent breakup. The latter phenomenon will be compared with statistical data from idealized numerical experiments.
Practical application of this research can be found in the physics of atmospheric clouds and the dynamics of sprays in turbulent fuel injection.
