Shake-The-Box: high-resolution Lagrangian particle tracking for large and small scale aerodynamics

Kurzfassung

Shake-The-Box is a 3D Lagrangian Particle Tracking method measuring position, velocity and acceleration along typically ~105 trajectories in a measurement volume instantaneously. Using HFSB and pulsed LED illumination large volumes in m³ -scales can be investigated in low-speed flows and multi-pulse STB approaches are available for high-speed aerodynamics. FlowFit, a data assimilation method using Navier-Stokes constraints, interpolates the scattered particle data and provides the full (coarse grained) time-resolved velocity gradient tensor and pressure fields. The STB methodology and examples of applications in various fields will be presented.
