Introduction

Underexpanded jets have been the subject of many studies for a long time. The most often encountered ones issue from a convergent nozzle. Indeed, it is enough that the nozzle pressure ratio (henceforth NPR), defined as the ratio of upstream stagnation pressure to the ambient pressure, be above a critical value, and the jet is underexpanded, the static pressure at the nozzle exit being higher than the ambient.
