dc.description.abstractA water tunnel flow visualization was performed to study the vortex development and bursting phenomena on a baseline double delta wing model and a modified double delta wing model. The primary focus of this study was two-fold: First, to study the static and dynamic effects of pitch and pitch rate on the vertical flowfield of the individual models. Second to compare the vortex breakdown characteristics of these two models under static and dynamic conditions. Results indicate that the vortex burst location moves forward with increasing AOA for both the models relative to the static case, the bursting is delayed during pitch up motion with the vortex burst lag increasing with the pitch rate. Compared with the baseline model, the small geometry model changes the local flowfield in developing the wing vortex earlier and promoting earlier coiling-up of strake and wing vortices.en_US
