A computational fluid dynamics study of hydrogen bubbles in an electrochemical reactor

Brazilian Archives of Biology and Technology, 2005
Most electrochemical reactors present reactions with the growth and departure of gas bubbles which influence on the reactor hydrodynamics and this study is usually complex, representing a vast field for research.

Determining ultrasonic propagation effective properties in complex heterogeneous media through microstructure-scale simulation

Research and Review Journal of Nondestructive Testing, 2023
Ray-based methods allow for fast computations of ultrasonic propagation in large components, and can be coupled with diffraction models to provide full simulations of NDE inspections.

Nonlinear elliptic problems with the method of finite volumes

Differential Equations and Nonlinear Mechanics, 2006
We present a finite volume discretization of the nonlinear elliptic problems. The discretization results in a nonlinear algebraic system of equations.

Machine learning rather than trial and error to close morphodynamical tuneable parameters: Application to a two-phase/two-layer model

Journal of Hydroinformatics
Physics-based numerical models often depend on several parameters to close. Some of them can be expressed using established theoretical or empirical closure formulations.

Finite volume effects near the chiral crossover [PDF]

EPJ Web of Conferences
The effect of a finite volume presents itself both in heavy ion experiments as well as in recent model calculations. The magnitude is sensitive to the proximity of a nearby critical point.

On the high order FV schemes for compressible flows [PDF]

Applied and Computational Mechanics, 2007
This work describes a high order finite volume scheme for compressible flows. The differences between the basic low order scheme and the second and third order schemes are documented for the case of inviscid flows in a channel as well as for the case of ...

From Statistical Correlations to Stochasticity and Size Effects in Sub-Micron Crystal Plasticity

Metals, 2019
Metals in small volumes display a strong dependence on initial conditions, which translates into size effects and stochastic mechanical responses. In the context of crystal plasticity, this amounts to the role of pre-existing dislocation configurations ...

Influence of cement-augmented pedicle screws with different volumes of polymethylmethacrylate in osteoporotic lumbar vertebrae over the adjacent segments: a 3D finite element analysis

BMC Musculoskeletal Disorders, 2020
Background Polymethylmethacrylate (PMMA) is commonly used for cement-augmented pedicle screw instrumentation (CAPSI) to improve the fixation stability and reduce the risk of screw loosening in the osteoporotic thoracolumbar spine.
