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...
Interdependent binary choices under social influence: phase diagram for homogeneous unbiased populations
Interdependent binary choices social influence phase diagram homogeneous unbiased populations Statistical Mechanics
2012/4/20
Coupled Ising models are studied in a discrete choice theory framework, where they can be understood to represent interdependent choice making processes for homogeneous populations under social influe...
Transient behavior of the thermocapillary migration of drops under the influence of deformation
Transient behavior the thermocapillary migration the influence of deformation Fluid Dynamics
2011/8/2
Abstract: The transient thermocapillary migration of drops with nontrivial deformation is studied. The finite difference method is employed to solve the incompressible Navier-Stokes equations coupled ...
Influence of specimen-reconstituting method on the undrained response of loose granular soil under static loading
Liquefaction Undrained Dry funnel pluviation Wet deposition Residual strength
2012/2/29
This paper describes the results of an experimental study on the undrained shear behaviour of loose sand collected from the location close to the epicenter of the recent Chlef (Algeria) Earthquake (Oc...
Investigation on the spurious eigenvalues of vibration plates by non-dimensional dynamic influence function method
Meshless Non-dimensional dynamic influence function method Plate vibration
2010/10/22
This paper makes a numerical investigation on the spurious eigenvalues problem by the
non-dimensional dynamic influence function (NDIF) method for plate vibration problems. We find
that the NDIF spu...
Influence of a cruciform arrangement downstream strip-plate on crossflow vibration of a square cylinder
flow induced vibration galloping longitudinal vortex vibration control vortex excitation
2010/3/11
In earlier works, the present authors found that the Kármán vortex excitation of a circular cylinder is effectively suppressed by setting another cylinder in cruciform arrangement downstream with a ga...
Thermal wall influence on the behavior of axisymmetric laminar compressible flow in nozzle
compressible Mac-Cormack scheme nozzle numerical study viscous flow wall
2010/3/11
The present work concerns a numerical study of an axisymmetric laminar flow of a compressible gas in a small size convergent-divergent nozzle. The geometry and the reservoir conditions are such that t...
Influence of cross-sectional configuration on Kármán vortex excitation
K¶ arm¶ an vortex excitation cross-sectional con¯ guration synchronization
2010/3/12
Three cylindrical bodies with di®erent cross{sectional con¯gurations, i.e. a circular, semi-circular and triangular cylinder, are used as the test cylinders, in order to investigate the in°ue...
