Multi-Step Structural Optimization Design of Multi-Bubble Pressure Cabin in the Autonomous Underwater Vehicle with Blended-Wing-Body [PDF]

Xibei Gongye Daxue Xuebao, 2018
In this paper, multi-bubble pressure cabin is proposed for the flat fuselage of blended-wing-body(BWB) autonomous underwater vehicle(AUV). It has strong compressive capacity and makes full use of the fuselage space.

Simulation and analysis of collapsing vapor-bubble clusters with special emphasis on potentially erosive impact loads at walls [PDF]

EPJ Web of Conferences, 2018
Cavitation is a process where a liquid evaporates due to a pressure drop and re-condenses violently. Noise, material erosion and altered system dynamics characterize for such a process for which shock waves, rarefaction waves and vapor generation are ...

Maximum entropy estimation of the bubble size distribution in fluidized beds [PDF]

, 2009
This work presents a new methodology, based on the maximum entropy method, to obtain bubble characteristics in fluidized beds. The probability distributions (PDF) of bubble pierced length and velocity are obtained applying the maximum entropy principle ...

Bubble-Growth for a Wetting System in the Maximum Bubble Pressure Method

Materials Transactions, JIM, 1999
This paper describes a new measuring apparatus for the maximum bubble pressure method to confirm the pressure change pattern during bubble formation for a wetting system. Generally speaking, a sawtooth pressure pattern has been widely accepted by many researchers.

Tensiometry as a Simple Analytical Method for Quantification of Solubility and Release of Aroma Molecules in Aqueous Media

Molecules, 2021
Dynamic tensiometry is shown to be a high-potential analytical tool in assessing physico-chemical characteristics of fragrance molecules, such as solubility limit, volatility as well as much rarely assessed interfacial activity of these amphiphilic ...

Bubble-Growth for Wetting and Nonwetting System in the Maximum Bubble Pressure Method

MATERIALS TRANSACTIONS, 2001
This paper describes a new measuring apparatus for the maximum bubble pressure method to confirm the pressure change pattern during bubble formation for wetting and nonwetting systems. Generally speaking, a sawtooth pressure pattern has been widely, accepted by many researchers in the maximum bubble pressure method.

Surface Tension of Baked Food Batter Measured by the Maximum Bubble Pressure Method [PDF]

Agricultural and Biological Chemistry, 1991
The surface tension (σ) of batter prepared with one or two of the major ingredients of wheat flour, egg and sucrose was measured by the maximum bubble pressure method. The surface tension of the soft- and hard-wheat flour suspension decreased as the solid content of wheat flour was increased, finally reaching 48.2 and 52.7 dyn/cm, respectively.

Dynamic Surface Tension of Aqueous Solutions of Ionic Surfactants: Role of Electrostatics [PDF]

, 2010
The adsorption kinetics of the cationic surfactant dodecyltrimethylammonium bromide at the air-water interface has been studied by the maximum bubble pressure method at concentrations below the critical micellar concentration.
