Free Surface Flows with Moving and Deforming Objects for LBM
We will present an algorithm to handle moving and deforming objects for free surface fluid simulations with the lattice Boltzmann method (LBM). To achieve this we extend methods available for flows without a free surface to enables simulations of moving objects with varying surface roughness, two-way coupled interaction and improved mass conservation. We furthermore show how to efficiently init...
متن کاملSimulation of Gravity Wave Propagation in Free Surface Flows by an Incompressible SPH Algorithm
This paper presents an incompressible smoothed particle hydrodynamics (SPH) model to simulate wave propagation in a free surface flow. The Navier-Stokes equations are solved in a Lagrangian framework using a three-step fractional method. In the first step, a temporary velocity field is provided according to the relevant body forces. This velocity field is renewed in the second step to include t...
متن کاملSimulations of 3D non-hydrostatic free surface flows with SPH
In this paper, the application of a new robust and accurate SPH scheme proposed by Ferrari et al. [1] is presented. It provides good accuracy for computing complex 3D non-hydrostatic free surface flows. This has been assesed by the comparison of the numerical solutions of dam-break and impact-wave problems against experimental data and reference solutions. Moreover, to improve considerably the ...
متن کاملA New 3D Parallel SPH scheme for Free Surface Flows
The focus of the research activity is on the Smoothed Particle Hydrodynamics (SPH) method and its applications to environmental flow problems. The purpose is to model fully three-dimensional non-hydrostatic free surface flows and impact problems with the SPH method applying it to inviscid and viscous fluids. After a thorough literature review of the SPH method, the research work is divided up i...
متن کاملImproved SPH methods for simulating free surface flows of viscous fluids
In this paper we present two enhanced variants of the smoothed particle hydrodynamics (SPH) method for the numerical simulation of free surface flows of viscous fluids. Improvements are achieved by deriving a new set of general discrete SPH-like equations under an energy-based framework and applying a corrected (high-order) or coupled particle approximation scheme for function derivatives. By d...
