The physical mechanism for vortex merging
C Cerretelli, CHK Williamson - Journal of Fluid Mechanics, 2003 - cambridge.org
In this paper, we study the interaction of two co-rotating trailing vortices. It is well-known that
vortices of like-sign ultimately merge to form a single vortex, and there has been much work …

The mixing layer over a deep cavity at high-subsonic speed
N Forestier, L Jacquin, P Geffroy - Journal of Fluid Mechanics, 2003 - cambridge.org
The flow over a cavity at a Mach number 0.8 is considered. The cavity is deep with an aspect
ratio (length over depth) L/D= 0.42. This deep cavity flow exhibits several features that …
