Fuel Tank Vertical Sloshing during Aircraft Landing

Xibei 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

, 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.

Inviscid SPH

, 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 ...
