| Description
| - Příspěvek se zabývá experimentálním sledováním kolizí bubliny s hydrofilním vodorovným povrchem. Konečná rychlost bubliny, rychlost při nárazu, kontaktní čas, deformace bubliny a rychlost bubliny při odrazu byly vyhodnoceny (pomocí rychloběžné kamery) v závislosti na velikosti bubliny (v rozmezí 0.4 až 1.1 mm). Experimentální data jsou porovnávány s modelem Legendra a kol. (Phys. Fluids 17, 2005). Data pro kontaktní čas bubliny se stěnou jsou v dobrém souladu s modelem, zatímco data pro rychlost nárazu a odrazu se významně liší. Tento nesoulad je pravděpodobně způsoben omezenou platností předpokladů modelu, který byl odvozen pro interakce kapka-stěna. Rozdíl mezi modelem a experimentálními daty může být vysvětlen zejména zanedbáním vztlakové síly, nekulového tvaru bubliny a uvažováním pouze malých deformací bubliny. (cs)
- The contribution deals with the experimental investigation of collision of a gas bubble with a hydrophilic (glass) horizontal surface. The terminal bubble velocity, impact velocity, contact time, bubble deformation and restitution velocity are evaluated (by means of a high-speed camera) as a function of bubble size, which is ranging from 0.4 to 1.1 mm. The experimental results are compared with the model of Legendre et al. (Phys Fluids 17, 2005). The data on contact time agree well with the model predictions, while they vary significantly in the case of impact velocity and restitution velocity. This disagreement is probably caused by limited validity of assumptions of the model, which was developed for the drop-wall interaction. Especially the neglect of buoyancy, bubble non-sphericity and consideration of small deformations in the model could explain the difference.
