Time-accurate Aerodynamic Modeling of Synthetic Jets for Flow Control

This paper describes a computational study undertaken to determine the aerodynamic effect of tiny unsteady synthetic jets as a means to provide the control authority needed to maneuver a spinning projectile at low subsonic speeds. Advanced Navier-Stokes computational techniques have been developed and used to obtain numerical solutions for the unsteady jet-interaction flow field at subsonic spe...

Conical Flow induced by Quenched QCD Jets

Quenching is a recently discovered phenomenon in which QCD jets created in heavy ion collisions deposit a large fraction or even all their energy and momentum into the produced matter . At RHIC and higher energies, where that matter is a strongly coupled Quark-Gluon Plasma (sQGP) with very small viscosity, we suggest that this energy/momentum propagate as a collective excitation or “conical flo...

Vectoring of Adjacent Synthetic Jets

The formation, evolution, and interactions of a closely spaced pair of coflowing rectangular synthetic jets are investigated using particle image velocimetry. The dynamics of the combined jet is determined by the interactions of the counter-rotating vortex pairs that form each jet. These vortex pairs are formed along the long edges of the orifice of each jet by the time-periodic motion of a dia...
