(author), Schneiders, J.F.G. (author), Schrijer, F.F.J. (author)A test case for pressure field reconstruction from particle image velocimetry (PIV) and Lagrangian particle tracking (LPT) has been developed by constructing a simulated experiment from a zonal detached eddy simulation for an axisymmetric base flow at Mach 0.7. The test case comprises sequences of four subsequent particle images (representing...journal article 2017

(author), Schrijer, F.F.J. (author)A test case for PIV-based pressure evaluation techniques has been developed by constructing a simulated experiment from a ZDES simulation for an axisymmetric base flow at Mach 0.7. The test case comprises sequences of four subsequent particle images (representing multi-pulse data) as well as continuous time-resolved data. Particle images were...conference paper 2016

Roosenboom, E.W.M. (author), Geisler, R. (author), Agocs, J. (author), Schanz, D. (author), Weikert, T. (author), Kirmse, T. (author), Schröder, A. (author)Multiple optical measurement techniques have been applied for the investigation of a propeller-wing wind tunnel model. The (half) wind tunnel model is equipped with a nine bladed propeller and its wing has active Coanda blowing over the whole span of the wing. The aim of the investigation is to gain understanding of the flow phenomena,...conference paper 2013

Schröder, A. (author), Schanz, D. (author), Geisler, R. (author), Willert, C. (author), Michaelis, D. (author)A demonstration experiment and first assessment of a dual-volume and four-pulse tomo PIV system operating with two pairs of perpendicularly polarized laser light pulses and respective polarizing filters for separation of the scattered particle light is presented. The polarizing filters are placed in front of eight sCMOS double-frame cameras...conference paper 2013

Schanz, D. (author), Schröder, A. (author), Gesemann, S. (author), Michaelis, D. (author), Wieneke, B. (author)A novel approach to the evaluation of time resolved particle-based tomographic data is introduced. By seizing the time information contained in such datasets, a very fast and accurate tracking of nearly all particles within the measurement domain is achieved at seeding densities comparable to (and probably above) the thresholds for tomographic...conference paper 2013

Ehlers, H. (author), Agocs, J. (author), Konrath, R. (author), Korkischko, I. (author), Schanz, D. (author), Geisler, R. (author), Willert, C. (author), Wokoeck, R. (author)Three-dimensional, unsteady flow fields of a pitching low aspect ratio wing were measured by tomographic PIV [6] in air. The analysis of the vortex dominated flow field provides a deeper understanding of vortex interaction and three-dimensionality of the low Reynolds number (Re ? 10,000) flow. In order to recover the complete flow field the...conference paper 2013
