Major Goals The primary goal of this equipment grant is to acquire, commission and train junior and senior researchers on the use of a tomographic Particle Image Velocimetry tomo-PIV system for volumetric measurements of three components of velocity within flow fields.Accomplishments The target tomo-PIV system was purchased and delivered before the end of 2018. The system, which was ordered from LaVision, was set up with the help of Dr. Douglas Neal from LaVision for use with a 15 cm x 15 cm water tunnel by March of 2019. Subsequently, the functionality of all components was checked by Dr. Neal in collaboration with two postdocs of the PIs. Dr. Neal also conducted a full-day training session in March 2019 on the use of the hardware and the software of the tomo-PIV system. A few graduate students, postdocs and the lead PI Naguib attended the training. Presently, the system is being used to measure the near-wake flow field of a cylinder with surface topology see uploaded file for a brief description of the setup with images. These measurements are intended to enhance the outcome of an army-funded project that is motivated by understanding flow-induced vibrations of the suspension lines of Precision Air Drop Systems Grant number W911NF-17-1-0153. This project is also partially funded by U.S. Army CCDC-Soldier Center. Training Opportunities Three PhD students, Two postdocs and the lead PI Naguib were trained on the use of the acquired state of the art velocity-field-measurement equipment. The system will enhance the learning of future graduate and undergraduate students through demonstrations in our experimental fluid mechanics course, and the use of the equipment in research.
