Shock wave absorption in liquid foams

Résumé

Liquid foams are, amongst other usage, used to mitigate shock waves during mine-cleaning operations due to their excellent ability to absorb energy. However, the origins of this important property are still not well understood. We use a shock tube to send a shock wave on a foam sample with controlled liquid fraction and bubble size. We record images with a high speed ca- mera and pressure signals through the sample, giving information about the wave propagation and attenuation, the foam displacement and the destroyed area.
