Recent Advances in Volumetric Flow Measurements: High-Density Particle Tracking ('Shake-The-Box') with Navier-Stokes Regularized Interpolation ('FlowFit')

摘要

An overview is given of the novel Lagrangian particle tracking method 'Shake-The-Box', which allows particle tracking at high particle image density. The regularized interpolation of the discrete tracking information onto an Eulerian grid (FlowFit) shows an unprecedented spatial resolution. Application of the methods on two different experimental cases is briefly outlined.
