Transverse Waves in Simulated Liquid Rocket Engines [PDF]

open access: possibleAIAA Journal, 2011
This work seeks to provide a closed-form analytical solution for the transverse vorticoacoustic wave in a circular cylinder with headwall injection. This particular configuration mimics the conditions leading to the onset of traveling radial and tangential waves in an idealized liquid rocket engine.
