Aeroacoustics of axisymmetric single and dual flow exhaust nozzles

13th Propulsion Conference, 1977
A systematic approach to the prediction of jet noise has been developed for conical, conventional bypass, and inverted-flow bypass nozzles. The prediction involves computation of the mean velocity, temperature, and relevant turbulence properties throughout the jet. Each turbulent eddy volume in the jet is treated as a statistically independent radiator

Characterisation of subsonic axisymmetric nozzles

Chemical Engineering Research and Design, 2008
Abstract Nozzles are simple devices often used in chemical engineering, mainly either as flow rate sensors or as various jet generating actuators. This paper discusses the question of characterising their steady-state behaviour by a numerical value—or perhaps by a few values.

Mach Disk from Underexpanded Axisymmetric Nozzle Flow

AIAA Journal, 1974
The flowfield associated with the underexpanded axisymmetric nozzle freejet flow including the appearance of a Mach disk has been studied. It is shown that the location and size of the Mach disk are governed by the appearance of a triple-point shock configuration and the condition that the central core flow will reach a state of 'choking at a throat'.

Role of Wall Shape on the Transition in Axisymmetric Dual-Bell Nozzles

Journal of Propulsion and Power, 2005
Dual-bell nozzles represent a possible solution to improve the performance of large liquid rocket engines for launcher first stages. The present paper studies the role of the second bell shape on the side loads that can occur during the transition between the two main operating modes of the nozzle.
