Numerical analysis of transient combustion response to acoustic oscillations in axisymmetric rocket motors [PDF]
, 1998 A numerical analysis of unsteady motions in solid rocket motors with a nozzle has been conducted. The formulation treats the complete conservation equations for the gas phase and the one-dimensional equations in the radial direction for the condensed

Numerical simulation of axisymmetric valve operation for different outer cone angle
EPJ Web of Conferences, 2017 One of the method of flow separation control is application of axisymmetric valve. It is composed of nozzle with core. Normally the main flow is attached to inner cone and flow by preferential collector to primary flow pipe.

Instability waves in a subsonic round jet detected using a near-field phased microphone array [PDF]
, 2006 We propose a diagnostic technique to detect instability waves in a subsonic round jet using a phased microphone array. The detection algorithm is analogous to the beam-forming technique, which is typically used with a far-field microphone array to ...
