This paper describes the flowfield characteristics of the flip-flop jet nozzle and the potential for using this nozzle as a practical excitation device.

A jet is emitted from a primary nozzle exit into the flip-flop jet nozzle with an inlet spatially-averaged velocity U in at the nozzle exit. Such a confined jet sometimes oscillates at a dominant frequency f D in the presence of a.

To reveal the oscillation mechanism of a flip-flop-jet nozzle with a connecting tube, the authors assume that the jet switches when a time integral reaches a certain value. As the time integral, we consider the accumulated flow work of pressure, namely, the time integral of mass flux through a connecting tube into the jet-reattaching wall from Author: Tatsuya Inoue, Katsuya Hirata.

In an attempt to resolve some of the technological challenges on supersonic aircraft design, a substantial revision of the existing concept is required.

In this paper critical review of the literature is carried out and a conceptual design of short takeoff supersonic aircraft with cold flow multi-purpose rectangular nozzle has been proposed. An annular nozzle has been designed on the basis of fluidic principles. The nozzle forms actively controlled air jet.

Numerical and experimental investigations were performed in several subsequent steps, namely numerical simulation (using a commercial CFD code FLUENT), geometry adaptation, models manufacturing, flow visualization, hot-wire measurement, and Cited by: This banner text can have markup.
