November 2024: Jet flows can be found all around us both in industrial applications (e.g. jet propulsion, impinging jet cooling), human health (e.g. drug delivery devices, virus spread through coughing), and environmental settings (e.g. volcano eruptions). Although particle-laden jets have been studied extensively during the last decades, still little is known about polydisperse particle-laden jets in the two-way coupling regime. This research will leverage combined inline digital holographic cinematography with high-speed stereoscopic particle image velocimetry (stereo-PIV) to resolve the spatio-temporal distributions of both the beads and the surrounding flow field. The focus of the research will be on polydisperse spherical beads in the two-way coupling regime for which hardly any data exists.
