In shear flows like pipe flow and plane Couette flow there is an extended range of parameters where linearly stable laminar flow coexists with a transient turbulent dynamics. When increasing the amplitude of a perturbation on top of the laminar flow, one n ...
We propose a new fluid control technique that uses scale-dependent force control to preserve small-scale fluid detail. Control particles define local force fields and can be generated automatically from either a physical simulation or a sequence of target ...
This is a numerical investigation of a yield-stress fluid flowing down an inclined plane. A three-dimensional, free-surface, two-phase incompressible Navier-Stokes solver is extended to handle generalized Newtonian fluids. Special attention is spent on the ...
A 2D numerical flow model, developed at the Research unit of Hydrology, Applied Hydrodynamics and Hydraulic Constructions at ULg, has been applied to flows in a macro-rough channel. The model solves the shallow water equations (SWE) with a two length scale ...
In this work we use the Smoothed Particle Hydrodynamics methodology (SPH) to simulate incompressible viscous flows of Newtonian fluids. The SPH is a meshfree Lagrangian method which simulates the flow like a set of moving fluid particles that interact one ...
In this work we focus on the modeling and numerical simulation of the fluid-structure interaction mechanism in vascular dynamics. We first propose a simple membrane model to describe the deformation of the arterial wall, which is derived from the Koiter sh ...
The study considers algebraic turbulence modeling in adiabatic gas-liquid annular two-phase flow. After reviewing the existing literature, two new algebraic turbulence models are proposed for both the liquid film and the droplet laden gas core of annular t ...
Pseudospectral methods are frequently used in the horizontal directions in large-eddy simulation of atmospheric flows. However, the same approach often creates unphysical oscillations for scalar fields if there are horizontal heterogeneities in the sources ...
With the development of numerical tools used to simulate fluid-structure interactions phenomena, investigations on hydrodynamic damping are now more accessible and the studied cases are more flexible. The aim of the present study is, at first, to analyze t ...
The parallelized model is first presented and a scalability study is achieved. For computational time saving and memory requirement reasons, the implementation of a three dimensional SPH code implies the need for its parallelization, in order to make possi ...
