The modelling of complex free surface flows is challenging due to the mobility and deformability of the interface and air entrainment characteristics, which are highly affected by turbulence. With the framework of Reynolds averaged Navier–Stokes (RANS) models and the volume of fluid (VOF) method, turbulence quantities at the air–water...

This paper presents a new monolithic free-surface formulation that exhibits correct kinetic and potential energy behavior. We focus in particular on the temporal energy behavior of two-fluids flow with varying densities. Correct energy behavior here means that the actual energy evolution of the numerical solution matches the evolution as...

In this work the feasibility of a numerical wave tank using a hybrid particle-mesh method is investigated. Based on the Fluid Implicit Particle Method (FLIP) a generic formulation for the hybrid method is presented for incompressible multi-phase flows involving large density jumps and wave generating boundaries. The performance of the method...

Extending the weldability of novel materials, and improving the weld quality by tailoring weld microstructures are key factors to obtain the welding techniques demanded in the modern manufacturing industries. This can be done, for example, by feeding chemical elements from a consumable wire into the weld pool during welding. The mixing of...

Surface capturing is a technique for modelling the water surface in numerical computations of water flow: the computational grid is not deformed, a separate surface model gives the location of the water surface in the grid. Surface capturing is generally applicable and can handle complicated ship geometries. For steady flow problems, the major...

Non-linear free-surface phenomena, such as extreme waves and violent sloshing, and their impact on the dynamics response of the containing vessels have long been subjects that could only be studied with experimental methods. Nowadays, computational CFD tools can make a significant contribution to these flow problems. The paper starts with a...

This work presents a numerical method for solving three-dimensional viscoelastic free surface flows governed by the Oldroyd-B constitutive equation. It is an extension to three dimensions of the technique introduced by Tomé et al. [1] (see also [5]). The governing equations are solved by a finite difference method on a 3D-staggered grid. Marker...

With the increasing amount of liquid on board spacecraft, liquid management and its influence on the overall spacecraft dynamics is becoming increasingly important. The influence of sloshing liquid may hamper critical manoeuvres in space, such as the docking of liquid-cargo vehicles (e.g. to ISS) or the pointing of observational satellites....

The paper concerns modeling of two-phase flow with the volume of fluid method (VOF) and two high-resolution advection schemes based on the normalized variable diagram (NVD). Compressive Interface Capturing Scheme for Arbitrary Meshes (CICSAM) and High Resolution Interface Capturing scheme (HRIC). Both considered schemes are used to discretize...

We introduce a monotonic and conservative numerical scheme for the resolution of the linear advection problem set on a moving domain. The scheme is based on an extension to moving domains of the Multidimensional Upwind Residual Distributive (MURD) approach. The properties ensured by the residual distribution schemes set on fixed domains are not...

The modelling of magnetohydrodynamics (MHD) phenomena in aluminium electrolysis cells is a challenging problem. The basic equations are the MHD equations in parabolic form, for two immiscible fluids. Among the various nonlinearities in the model, one is due to the moving interface between the two fluids. The basic question that numerical...

A time dependent Computational Fluid Dynamics analysis of gas jets impinging onto liquid pools has been conducted. The aim of the study is to obtain a better understanding of highly complex, and industrially relevant flows in jetting system. Three different multiphase models, i.e., The Eulerian model, the volume of fluid model and the mixture...

A boundary element method has been developed that can be used to calculate two-dimensional potential flow phenomena with a free surface. The unsteady Bernoulli equation is applied at the actual position of the free surface. A solution for corners arising in the geometry of the boundary has been found. Comparison of results of the present model...
