Fracture dominant in friction stir spot welded joint between 6061 aluminum alloy and galvannealed steel based on microscale tensile testing

open access: yesMaterials & Design, 2022
The macroscale mechanical properties of dissimilar joints are generally influenced by the fracture behavior of joint interface. However, little is known about the dominant factor for the joint properties related with both macroscale fracture behavior and

The significance of grouping and missed bubbles on interfacial area concentration and void fraction [PDF]

open access: yes, 2018
The two-fluid model is used in nuclear reactor safety codes. Two of the important constitutive relations will be discussed in this study, the interfacial area concentration and void fraction. The Interfacial area concentration is directly affected by the

Measurements of interfacial area concentration in two-phase flow with two-point conductivity probe. Brief communication

open access: yes, 1997
Kataoka, Ishii and Serizawa analyzed the measurements of the local time-averaged interfacial area concentration in two-phase flow with a two-point conductivity probe. They considered the influence of the bubble velocity fluctuation on the measurement and

Temperature Effects on Interfacial Area Concentration and Void Fraction in LBE-N2 Bubbly Flow

open access: yesApplied Sciences
Temperature-dependent local two-phase flow parameters in lead–bismuth eutectic (LBE)–gas bubbly flows are essential for validating the closure models used in safety analyses of steam generator or heat exchanger tube rupture accidents in lead-cooled fast ...

Interfacial Area Transport of Vertical Upward Bubbly Flow in an Annulus [PDF]

open access: yes, 2002
In relation to the development of the interfacial area transport equation, hydrodynamic separate tests without phase change were performed in an adiabatic air-water bubbly flow in a vertical annulus to identify the effect of bubble coalescence and ...
