Summary
[edit]DescriptionTwo undercompressive shocks.jpg |
English: In this photograph (Laboratoire de Physique de la Matière Condensée, Collège de France, 1999) we see a bulge of liquid. It rises on a solid plate by thermal Marangoni effect. Black and shiny fringes are fringes of equal thickness, obtained through interference from a Laser beam.
The liquid front at the top is an undercompressive shock, similar to the shocks observed by Fanton and Cazabat and by Ludviksson and Lightfoot. Below is another type of undercompressive shock, a reverse one. Here it is unstable and gives birth to tears. It is theoretically stable, but the experimental method didn't allow to observe this stability. The same undercompressive shock has been observed by Bertozzi a few years later, with a better method. |
