An Innovative Approach to Nonintrusive Quantitative Measurements of Vortex Flows
Abstract
A unique flow measurement technique was used to obtain quantitative vortex flow field data. This demonstration demonstrated that a video based data acquisition system, Expertvision, could be used to measure the velocity of flow through some parts of the flow field. The system systematically tracks packets of colored dye ejected from the models into there surrounding flow fields and then subsequently reduces the data to position, velocity and acceleration measurements for individual vortex cores. Vortex core data were collected for 70 and 80 degree delta wing models with both stationary and forced roll oscillation roll conditions. Keywords: Flow visualization, Flow measurement, Vortex flow.
