High Resolution and High-Speed Live Optical Flow Velocimetry
Juan Pimienta, Jean-Luc Aider
Particle Image Velocimetry (PIV) typically relies on cross-correlation,which makes it difficult to obtain instantaneous velocity fields that are both spatially dense and available…

Rare-event detection in a backward-facing-step flow using live optical-flow velocimetry: observation of an upstream jet burst
Juan Pimienta, Jean-Luc Aider
Rare and extreme events in turbulent flows play a critical role in transport, mixing and transition, yet are notoriously difficult to capture experimentally. Here we report, to our…
