Outline of Final Research Achievements

The influence of the oscillation characteristics and the asymmetry of slot geometry on the jet structure were investigated to establish the fundamental technologies of the flow control or the attitude control for thrusters using synthetic jets. Especially, some discussions on the jet vectoring to determine the fluid force direction were made. It was clarified that the travel direction of the continuous jets did not drastically depend on asymmetric slot, and on the other hand, the degree of deflection of synthetic jets produced with asymmetric slot could be controlled by the dimensionless frequency under the present condition range.
