movie1

Pressure contours along the duct at successive instants in time showing the development of the convective instability for the MSD liner and for a harmonic source. The Mach number is 0.3. The movie is related to Figs. 8, 9, 10, and 11.

movie2

Pressure contours along the duct at successive instants in time showing the development of the convective instability for the MSD liner and for an impulsive source.The Mach number is 0.3. The movie is related to Fig. 4(b).

movie3

Pressure contours at successive instants in time for the NASA GIT experiment with the CT57 liner: (top) without the GTS method and (bottom) with the GTS method. The Mach number is 0.335. The movie is related to Fig. 20.
