"WebThe ﬁrst objective of this work is to investigate the key non-linear processes occurring during the early stages of breakdown toward turbulence in hypersonic boundary layers. Speciﬁcally, we seek to contrast the non-linear breakdown physics in incompressible and compressible ﬂows. The focus is on pressure-related non-linear processes.
