Assessment of propeller induced properties and active flow control using multiple image-based measurement systems

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,...

Dual-Volume and Four-Pulse Tomo PIV using polarized laser light

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...
