The Vortex-Induced Vibration (VIV) of a circular cylinder with different surface roughness is numerically simulated at a subcritical Reynolds number of 3900.
Abstract. Wake fields due to the wall roughness of the vacuum chamber can catch up to the bunch causing energy spread and emittance growth.
The combined effects of discrete surface roughness and unsteady wake forcing on the development of laminar separated boundary layer will be studied using direct ...
The results show that the increasing roughness causes the delayed boundary layer separation, which causes the lower mean drag coefficient (CD), root-mean-square ...
In 3D simulations the surface roughness is represented by randomly distributed obstacles. We show two simulations with few obstacles. In one case the wake field.

This study uses a series of numerical simulations to examine the structure of the wake of the Hawaiian island of Kauai. The primary focus is on the ...
The main simulation is performed by using the spectral element code Nek5000. While in the laminar-inflow simulation the horseshoe vortex forming around the ...
This paper summarises the progress achieved in the study of passive scalars in flows over rough surfaces thanks to recent numerical simulations.
The direct numerical simulation of an accelerating boundary layer over a rough wall has been carried out to investigate the coupling between the effects of ...
