Abstract: The paper describes the characteristics of a wall-reattachment fluid amplifier. The switching of the jet from the wall to which it is attached to the opposite one is analyzed. It is shown that the control input characteristic that is measured statically can be applied in the dynamic case. This fact is far from being trivial, as the transient flow patterns occurring during the switching process are basically different from the stationary patterns. The variation of the response time (time interval between when a control pulse is applied at the control port and when the output signal is received at the other receiver) with the control supply pressure is given and compared with the results obtained from a simple analytical switching model. For a control supply pressure of 40 percent of the supply pressure, the response time is 5 to 8 times the transport time of a particle traveling 20 times the nozzle distance.
