Open-source software for modelling of free surface flows

open access: yesТруды Института системного программирования РАН, 2018
Problems of free-surface flow of viscous incompressible fluid are very useful in different practical cases. There are many specifies and limitations in these problems which are critically important for correct solving.

Beyond VoF: alternative OpenFOAM solvers for numerical wave tanks [PDF]

open access: yesJournal of Ocean Engineering and Marine Energy, 2020
AbstractThe vast majority of numerical wave tank applications are solved using finite volume-based, volume of fluid methods. One popular numerical modelling framework is OpenFOAM and its two phase solvers, interFoam and interIsoFoam, enabling the simulation of a broad range of marine hydrodynamic phenomena.

Three-Bladed Horizontal Axis Water Turbine Simulations with Free Surface Effects

open access: yesInternational Journal of Applied Mechanics and Engineering, 2021
The water level above a hydrokinetic turbine is likely to vary throughout the season and even along the day. In this work, the influence of the free surface on the performance of a three bladed horizontal-axis turbine is explored by means of a three ...

Fluid-structure interaction simulation of prosthetic aortic valves : comparison between immersed boundary and arbitrary Lagrangian-Eulerian techniques for the mesh representation [PDF]

open access: yes, 2016
In recent years the role of FSI (fluid-structure interaction) simulations in the analysis of the fluid-mechanics of heart valves is becoming more and more important, being able to capture the interaction between the blood and both the surrounding ...

On algebraic TVD-VOF methods for tracking material interfaces

open access: yes, 2019
We revisit simple algebraic VOF methods for advection of material interfaces based of the well established TVD paradigm. We show that greatly improved representation of contact discontinuities is obtained through use of a novel CFL-dependent limiter ...

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

open access: yes, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-

Computational Investigation of Liquid Holdup and Wetting Efficiency Inside Trickle Bed Reactors with Different Catalyst Particle Shapes

open access: yesApplied Sciences, 2020
Liquid holdup and wetting efficiency are essential parameters for design of trickle bed reactors. Both parameters play an important role in reactor performance including pressure drop, conversion, and heat transfer.

Intensification of the Near Wall Collapsing Bubble Induced Jet Using an Opposite Secondary Wall

open access: yesJournal of Fluid Science and Technology, 2008
Effects of an opposite secondary wall for intensification of the liquid jet that is formed through the near wall bubble collapse were numerically investigated. The axisymmetric form of the Navier-Stokes equations was solved to predict the flow conditions
