3D Lagrangian Particle Tracking in Fluid Mechanics

In the past few decades various particle image–based volumetric flow measurement techniques have been developed that demonstrated their potential in accessing unsteady properties quantitatively experimental applications fluid mechanics. this review, we focus on physical and circumstances of 3D particle–based measurements what knowledge can be used for advancing reconstruction accuracy spatial temporal resolution, as well completeness. The natural candidate our is Lagrangian tracking (LPT), which allows position, velocity, acceleration to determined alongside a large number individual tracks investigated volume. advent dense LPT technique Shake-The-Box decade has opened further possibilities characterizing flows by delivering input data powerful assimilation use Navier–Stokes constraints. As result, high-resolution Eulerian obtained, including long trajectories embedded time-resolved velocity pressure fields.
