Lagrangian Physics


I am working on the time-resolved three-dimensional Particle Tracking Velocimetry (4D-PTV), also known as Lagrangian Particle Tracking (LPT). With the Shake The Box (STB) inspiration, I am interested in new complementary tracking ideas to understand new Lagrangian physics. My main motivation for running the 4D-PTV website is to provide enough information including articles, theses, codes, positions, events, and so forth, as a shortcut for interested researchers in the PTV/LPT community.
