Wall Bounded Streamwise Vortex Destruction
Abstract
Wall-bounded streamwise vortex destruction methods were explored using unsteady jets. In application, wall-bounded vortex structures can reduce lift, increase drag, and also decrease stability. In our experiments, we generate longitudinal streamwise vortex structures using tabstyle rectangular vortex generators. Downstream, we use unsteady jets---commonly referred to as synthetic jets---to destroy the incoming vortex structure. Vortex generator interaction with an unsteady jet shows that the synthetic jet can diminish the coherent vorticity of pre-existing vortex structure. We explore a parameter space of rectangular jet orifice pitch and skew angles to inhale coherent vortex structure and exhale weaker vortex structure. Different jet and vortex generator combinations were experimentally explored using particle image velocimetry. All jet orientations were capable of diminishing the incoming coherent vortex structure.
