My work is mainly experimental. Most of our meausrements are achieved using optical techniques.

We use classic Particle Image Velocimetry setups, with either 15Hz or 1kHz sampling rates.

We also use less conventional techniques, like volumetric velocimetry, real-time high frequency PIV, micro-PIV or high frequency Schlieren visualizations.

Example of visualization of a micro-jet using Schlieren visualization and phase averaging. Thanks to this experimental approach, the axis switching of the micro-jet has been observed for the first time :
