High-resolution simulations of the flow around an impulsively started cylinder using vortex methods
TL;DR: In this paper, the development of a viscous incompressible flow generated from a circular cylinder impulsively started into rectilinear motion is studied computationally, and an adaptative numerical scheme based on vortex methods is used to integrate the vorticity/velocity formulation of the Navier-Stokes equations for a wide range of Reynolds numbers (Re = 40 to 9500).

Lattice Boltzmann Method on Curvilinear Coordinates System
Xiaoyi He,Gary D. Doolen +1 more
TL;DR: In this article, the lattice Boltzmann method is extended to apply to general curvilinear coordinate systems, and numerical simulations are carried out for impulsive initial conditions with Reynolds numbers up to 104.

The early stage of development of the wake behind an impulsively started cylinder for 40 Re 4
TL;DR: The time development of the symmetrical standing zone of recirculation, which is formed in the early stage of the flow due to a circular cylinder impulsively set in motion perpendicular to its generators, has been studied using a flow visualization technique.

Flow past an impulsively started circular cylinder
W. M. Collins,S. C. R. Dennis +1 more
TL;DR: In this article, the Navier-Stokes equations were integrated numerically for the time-dependent flow past an impulsively started circular cylinder, based on the diameter of the cylinder, from 5 to ∞.

Numerical study of flow past an impulsively started cylinder by the lattice-Boltzmann method
TL;DR: In this paper, a systematic numerical study of flow past an impulsively started circular cylinder at low and moderate Reynolds numbers using a lattice-Boltzmann algorithmic approach is presented together with an extended volumetric boundary scheme.
