On the sound of snapping shrimp
Michel Versluis, Barbara Schmitz, Anna von der Heydt +1
Fluid dynamics video: Snapping shrimp produce a snapping sound by an extremely rapid closure of their snapper claw. Our high speed imaging of the claw closure has revealed that the…
Non-Oberbeck-Boussinesq effects in turbulent thermal convection in ethane close to the critical point
Guenter Ahlers, Enrico Calzavarini, Francisco Fontenele Araujo +4
As shown in earlier work (Ahlers et al., J. Fluid Mech. 569, p.409 (2006)), non-Oberbeck Boussinesq (NOB) corrections to the center temperature in turbulent Rayleigh-Benard convect…
Dynamics of the spontaneous breakdown of superhydrophobicity
C. Pirat, M. Sbragaglia, A. M. Peters +4
Drops deposited on rough and hydrophobic surfaces can stay suspended with gas pockets underneath the liquid, then showing very low hydrodynamic resistance. When this superhydrophob…
Nanometer-Resolved Collective Micromeniscus Oscillations through Optical Diffraction
Helmut Rathgen, Kazuyasu Sugiyama, Claus-Dieter Ohl +2
We study the dynamics of periodic arrays of micrometer-sized liquid-gas menisci formed at superhydrophobic surfaces immersed into water. By measuring the intensity of optical diffr…
Spontaneous Breakdown of Superhydrophobicity
Mauro Sbragaglia, Alisia M. Peters, Christophe Pirat +4
In some cases water droplets can completely wet micro-structured superhydrophobic surfaces. The {\it dynamics} of this rapid process is analyzed by ultra-high-speed imaging. Depend…
Superstability of Surface Nanobubbles
Bram M. Borkent, Stephan M. Dammer, Holger Schoenherr +2
Shock wave induced cavitation experiments and atomic force microscopy measurements of flat polyamide and hydrophobized silicon surfaces immersed in water are performed. It is shown…
