A High-Order Spectral Difference Method for Fluid-Structure Interaction on Dynamic Deforming Meshes
High-Order Spectral Diff erence Method Fluid-Structure Interaction Dynamic Deforming Meshes
2015/7/3
In previous work by the authors, Spectral Difference Method has been formulated in a framework with time-dependent moving deformable meshes. The framework has also been shown to preserve the des...
Particle drift in turbulent flows: the influence of local structure and inhomogeneity
turbulent structures particle dispersion drift PDF approach
2012/5/31
The way particles interact with turbulent structures, particularly in regions of high vorticity and strain rate, has been investigated in simulations of homogeneous turbulence and in simple flows whic...
Arti cial analogues of natural-language phonological patterns can often be learned
in the lab from small amounts of training or exposure. The diculty of a featurally-

Abstract: Consider a Brownian particle in three dimensions which is attracted by a plane with a strength proportional to some dimensionless parameter $\alpha$. We investigate the fractal spatial struc...
Anomalous scaling and generic structure function in turbulence
turbulence Symmetry and conservation laws
2011/8/30
We discuss on an example a general mechanism of apparition of anomalous scaling in scale invariant systems via zero modes of a scale invariant operator. We discuss the relevance of such mechanism in t...
Periodic oscillation and fine structure of wedge-induced oblique detonation waves
Oblique detonation wave Wedge Periodic oscillation·Fine structure
2012/2/28
An oblique detonation wave for a Mach 7 inlet flow over a long enough wedge of 30 turning angle is simulated numerically using Euler equation and one-step rection model. The fifth-order WENO scheme is...
Study on fluid-structure interaction in liquid oxygen feeding pipe systems using finite volume method
Fluid-structure interaction Liquid oxygen Finite volume method
2012/2/29
The fluid-structure interaction may occur in space launch vehicles, which would lead to bad performance of vehicles, damage equipments on vehicles, or even affect astronauts' health. In this paper, an...
关于湍流中术语Coherent Structure的中文译法
2007/7/28
摘要 中文术语“拟序结构”来源于湍流研究中的英文术语“coherent structure”。 70年代初,对剪切层和自由射流的实验观察发现,这些湍流流动中存在着大尺度的涡旋结构。当初他们称之为大尺度“序的(ordered)”或“有组织的(organized)”结构,它对剪切流如混合层,边界层、射流和尾流的早期发展起着决定性的作用。1974年3月26—29日在英国Southampton召开的专题讨...
