Particle filtering with Lagrangian data in a point vortex model
… a technique used for state estimation from noisy measurements. In fluid dynamics, a popular problem called Lagrangian data assimilation (LaDA) uses Lagrangian measurements in the form of tracer positions to learn about the changing flow field. Particle filtering can be applied to LaDA to track the …

Lagrangian acceleration measurements via PTVA (Particle Tracking Velocimetry and Accelerometry) on a turbulent-like flow
… studied. To study those flows, an accurate Lagrangian technique to measure acceleration is needed: a novel technique, Particle Tracking Velocimetry and Accelerometry (PTVA), based on Image Analysis techniques, has been designed, developed and validated. PTVA is a self-adaptive methods which …
