HIGH FIDELITY DIAGNOSTICS AND TURBULENCE AT HIGH REYNOLDS NUMBER

Revealing new physics with highly resolved experimental techniques

Conventional probes and sensors suffer from limited spatiotemporal resolutions. This is especially true in high Reynolds number flows or in the near-wall regions of wall-bounded flows. The availability of Micro-Electro-Mechanical Systems (MEMS) technology enables mass-production of the next generation of sensors and diagnostics. Designing sensors at the micro and nanoscale not only enables significantly better spatiotemporal resolution but also unlocks previously unaccessible sensing modes
