Effects of vibrational nonequilibrium on the inviscid design of an axisymmetric nozzle for hypersonic flow [PDF]

open access: yes
An axisymmetric, hypersonic nozzle for arc-heated air is described. The method of characteristics is used to compute an inviscid nozzle contour in which vibrational nonequilibrium is approximated by the sudden-freeze technique.

The wall shear stress produced by the normal impingement of a jet on a flat surface [PDF]

open access: yes, 2000
A method for the theoretical determination of the wall shear stress under impinging jets of various congurations is presented. Axisymmetric and two-dimensional incompressible jets of a wide range of Reynolds numbers and jet heights are considered ...

Numerical study of acoustic oscillations and combustion instabilities in solid propellant rocket [PDF]

open access: yes, 1997
A numerical analysis of unsteady motions in solid rocket motors has been conducted. A fully coupled implicit scheme based on a dual time-stepping integration algorithm has been adopted to solve the governing equations and associated boundary conditions.

Numerical Study of Subsonic Hot and Near-Sonic Submerged Jets Based on a Two-Fluid Model [PDF]

open access: yesJournal of Applied and Computational Mechanics
This paper discusses the hot subsonic and near-sonic axisymmetric submerged stationary jets flowing from a nozzle with a radius of 25.4 mm. The Mach number at the nozzle exit is 0.376 for a subsonic jet, and for a near-sonic jet, it is 0.985.

A method for calculating a real-gas two-dimensional nozzle contour including the effects of gamma [PDF]

open access: yes
A method for calculating two-dimensional inviscid nozzle contours for a real gas or an ideal gas by the method of characteristics is described. The method consists of a modification of an existing nozzle computer program. The ideal-gas nozzle contour can
