Fuel Tank Vertical Sloshing during Aircraft Landing

open access: yesXibei Gongye Daxue Xuebao, 2020
In this article, the influence of the fuel sloshing on the tank under the landing condition is investigated to explain the skin deformation of wing tank. Based on the SPH method, a simplified fuel tank model of gas-liquid-solid three-phase is established.

CRKSPH - A Conservative Reproducing Kernel Smoothed Particle Hydrodynamics Scheme

open access: yes, 2016
We present a formulation of smoothed particle hydrodynamics (SPH) that utilizes a first-order consistent reproducing kernel, a smoothing function that exactly interpolates linear fields with particle tracers.

Resolving high Reynolds numbers in SPH simulations of subsonic turbulence

open access: yes, 2011
Accounting for the Reynolds number is critical in numerical simulations of turbulence, particularly for subsonic flow. For Smoothed Particle Hydrodynamics (SPH) with constant artificial viscosity coefficient alpha, it is shown that the effective Reynolds

Inviscid SPH

open access: yes, 2010
In smooth-particle hydrodynamics (SPH), artificial viscosity is necessary for the correct treatment of shocks, but often generates unwanted dissipation away from shocks. We present a novel method of controlling the amount of artificial viscosity, which uses the total time derivative of the velocity divergence as shock indicator and aims at completely ...

Modelling High Speed Machining with the SPH Method [PDF]

open access: yes, 2008
The purpose of this work is to evaluate the use of the Smoothed Particle Hydrodynamics (SPH) method within the framework of high speed cutting modelling. First, a 2D SPH based model is carried out using the LS-DYNA® software.
