Aerated food gels: fabrication and potential applications
R.N. Zúñiga,José Miguel Aguilera +1 more
TL;DR: Aerated gels contain both bubbles and entrapped water, thus offering ample versatility in product development as mentioned in this paper, and they may find applications in reducing the caloric density of foods and inducing satiety, as carriers of flavors and nutrients.

Bubble diameter on detachment in flowing liquids
R.A.M. Al-Hayes,R.H.S. Winterton +1 more
TL;DR: In this paper, an extensive series of measurements of gas bubble diameters on detachment into flowing liquids has been performed and new expressions were proposed for the surface tension and drag forces experienced by a bubble attached to a solid surface.

A new device for the generation of microbubbles
TL;DR: In this paper, the authors present a new method for the production of bubble-liquid suspensions (from now on BLS) composed of micron-sized bubbles and with gas to liquid volume ratios larger than unity.
Journal ArticleDOI
Modelling the bubble formation dynamics in non-Newtonian fluids
TL;DR: In this paper, a theoretical model is developed for modelling the non-spherical bubble formation at an orifice submerged in non-Newtonian fluids under constant flowrate conditions. But the model does not consider the influence of in-line interactions between bubbles due to the fluid memory effects of viscoelastic characteristics.
Journal ArticleDOI
Propagation of a topological transition: The Rayleigh instability
TL;DR: In this paper, a front propagation model for the Rayleigh instability of a cylindrical interface between two immiscible fluids is proposed, and numerical evidence that the viscous instability can spread behind a front moving at constant velocity, leading to a periodic sequence of pinching events.

Protein and surfactant foams: linear rheology and dilatancy effect
TL;DR: In this article, the dependence of foam rheology on the nature of its components (gas, liquid and surfactant) was investigated, and it was shown that the elastic modulus G �, once normalized by the Laplace pressure, does not depend on the foam components.
