Engineering Applications of Computational Fluid Mechanics, 2023 The motion response of a ship in a cross sea is studied based on computational fluid dynamics. Firstly, according to the established numerical pool, and based on the Reynolds-averaged Navier–Stokes equations and the re-normalisation group K–ϵ turbulence ...

Numerical investigation of air-entrainment in skimming flow over stepped spillways
Theoretical and Applied Mechanics Letters, 2016 As a widely used flood energy dissipator, the stepped spillway can significantly dissipate the kinetic or hydraulic energy due to the air-entrainment in skimming flow over the steps.

A penalization technique applied to the “Volume-Of-Fluid” method: wettability condition on immersed boundaries [PDF]
, 2014 A penalization approach is presented to simulate two-phase flow in the presence of immersed solid boundaries so as to consider highly complex objects such as porous media microstructures.

Computational fluid dynamics applied to gas-liquid contactors. [PDF]
, 1997 In this paper a `hierarchy of models¿ is discussed to study the fluid dynamic behaviour of gas-liquid bubble columns. This `hierarchy of models¿ consists of a Eulerian-Eulerian two fluid model, a Eulerian-Lagrangian discrete bubble model and a Volume ...

A Machine Learning Approach to Volume Tracking in Multiphase Flow Simulations
FluidsThis work presents a machine learning (ML) approach to volume-tracking for computational simulations of multiphase flow. It is an alternative to a commonly used procedure in the volume-of-fluid (VOF) method for volume tracking, in which the phase ...
