Analytical models for the boundary condition of a control by pulsed jets
by Patrick Gilliéron
International Journal of Aerodynamics (IJAD), Vol. 4, No. 1/2, 2014

Abstract: An analytical model is proposed to represent the evolution of the time-dependent flow rate in the exit plane of a two-dimensional pulsed jet. The actuator consists of a single channel and several closing equations are proposed. The channel geometry upstream of the exit plane consists of a succession of contractions and enlargements whose some dimensions vary with the closing equation. The influence of the closing equations on effective velocity, the fluid volume, volume flow rate and momentum injected into the flow on the half-period of closing and on the momentum coefficient are successively analysed and discussed.
