Lagrangian tracking

TīmeklisA typical time-resolved three-dimensional particle tracking velocimetry (4D-PTV) technique involves four recursive steps inspired by Shake The Box (STB), as shown … In experimental fluid mechanics, Lagrangian Particle Tracking refers to the process of determining trajectories of small neutrally buoyant particles (flow tracers) that are freely suspended within a turbulent flow field. These are usually obtained by 3-D Particle Tracking Velocimetry. A collection of such particle trajectories can be used for analyzing the Lagrangian dynamics of the fluid motion, for performing Lagrangian statistics of various flow quantities etc.
