Global instabilities in countercurrent jets

Physics of Fluids, 2002
Self-excited instabilities in supersonic, countercurrent (CC) jets are demonstrated based on numerical simulations, and it is argued that they can be used to explain unresolved discrepancies between laboratory and theoretical analysis. Self-excitation is based on upstream feedback mechanisms acting on the subsonic outer jet regions, and associated with

Global characteristics of jet impact

Journal of Fluid Mechanics, 1996
This paper is concerned with the impact of a jet of arbitrary cross-section onto a rigid plane. At the initial stage of the impact the liquid motion is described within the framework of the acoustic approximation. Behind the shock front which is generated under the impact, the pressure distribution is calculated analytically for an arbitrary cross ...

Global Flyer Jet Drag Chute System

19th AIAA Aerodynamic Decelerator Systems Technology Conference and Seminar, 2007
This paper describes the design, development and successful flight testing of a reliable, lightweight, highperformance prototype jet drag chute system for the Global Flyer Jet built by Scaled Composites. These drag chutes flew non-stop around the world in the Global Flyer jet piloted by Steve Fossett on a single tank of fuel in 2005, and for second ...

Global Instabilities in Wall Jets

2009
A wall jet, produced when fluid is blown tangentially across a flat surface, occurs in various applications. The linear instability of this flow has been studied under the assumption of locally parallel flow [2,4] and weakly non-parallel flow, i.e., using the parabolized stability equations (PSE) [7] but to our knowledge, its global stability has not.

Global stability analysis of underexpanded screeching jets

European Journal of Mechanics - B/Fluids, 2015
Abstract This article deals with a global stability analysis of the screech phenomenon. We have shown that a laminar underexpanded supersonic cold jet can exhibit globally unstable modes. A closer look at the structure of these modes shows that they present upstream propagating waves, which is known to be a major component of the screech phenomenon ...

Global confinement data: Joint european torus (JET)

Nuclear Fusion, 1990
(1) Three types of discharges have been chosen for JET. Within each discharge type, an approximate 'Greek-Latin square' with respect to the variables B, n, P and q has been constructed. The following features have been chosen to characterize the discharge type: material limiter ('limiter') or magnetic limiter ('X-point'); additional heating by RF waves
