Following a recent study of the authors, in which the evolution of the flow structures during the nozzle start-up of the Vulcain engine has been numerically simulated, this paper aims at indicating the different characteristic scales of the phenomena. The final goal is to find the possible conditions of a simultaneous occurrence of flow situations that can lead to dangerous forms of instability as the side load, and to indicate possible ways to predict and to avoid the problem.

Abstract

The final goal is to find the possible conditions of a simultaneous occurrence of flow situations that can lead to dangerous forms of instability as the side load, and to indicate possible ways to predict and to avoid the problem.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
