Abstract

The novel 30 Lagrangian Particle Tracking method "Shake-The-Box" (STB) is able to extract particle trajectories from volumetric flow measurements at unprecedented numbers. lt delivers accurate data on position, velocity and acceleration (material derivative) along these tracks. Subsequently, data assimilation approaches can be applied to the dense and scattered input data. An example is the "FlowFit" (FF) method, which uses Navier-Stokes-constraints for an interpolation of the flow field onto a regular grid in order to gain the full time-resolved velocity gradient tensor and pressure field with high spatial and temporal resolution. The STB method can be applied as weil to short recording sequences, acquired with multi-pulse techniques, allowing investigating high-speed flows at Reynolds numbers relevant for research in aerospace engineering. Recent developments of STB and FF will be presented here, along with data from accuracy studies using synthetic experiments and a range of experimental applications to turbulent flows in small and large scale volumes (up to cubic-meter-scales using HFSB seeding).
