Abstract

We present an overview of the activities of our group at DLR over the last three years in the field of volumetric flow measurements. Starting from experimental setups and evaluations using the techniques of tomographic PIV (TOMO-PIV) (1), a novel particle tracking method ('Shake-The-Box' (2)) was developed, which utilizes the temporal information residing in successive imaging of a consistent, dynamic particle distribution to enhance the reconstruction of each time step. By effectively separating true particles (which inside a volume cannot disappear in time) from false reconstructions ('ghost particles') the technique is able to process particle concentrations at least comparable to TOMO-PIV and more than one order of magnitude above the limits of typical 3D PTV.
