Figure

Fig. 1 is a reproduction of the high amplitude pulsations detected in Titan 4 SRM. One observes bursts of pulsations around the eigenfrequency of the first acoustic mode corresponding to a standing wave of approximately one half wavelength along the combust
Fig. 2 shows a sketch of the axial injection (1/30) scale model of the Ariane 5 booster used by Anthoine [17]
Fig. 4. Conformal mapping, Schwarz-Christoffel transformation of backward facing step with uniform approach flow
Fig. 5 shows the measurements from Anthoine [17] as a function of the Mach number for the second acoustic mode n = 2.
