Suppression of turbulence in wall‐bounded flows by high‐frequency spanwise oscillations
TL;DR: In this paper, the response of wall-flow turbulence to high-frequency spanwise oscillations was investigated by direct numerical simulations of a planar channel flow subjected either to an oscillatory spanwise crossflow or to the span-wise oscillatory motion of a channel wall.
Journal ArticleDOI
The MAC method
Sean McKee,Murilo Francisco Tomé,Valdemir Garcia Ferreira,José Alberto Cuminato,A. Castelo,Fabricio S. Sousa,Norberto Mangiavacchi +6 more
TL;DR: The Marker and Cell (MAC) method has been widely used in the field of flow visualization as mentioned in this paper. But it has not yet been applied to the analysis of surface and interfacial flows.
Journal ArticleDOI
A finite difference technique for simulating unsteady viscoelastic free surface flows
TL;DR: In this article, a numerical method capable of simulating viscoelastic free surface flow of an Oldroyd-B fluid was developed for the computation of the non-Newtonian extra-stress components on rigid boundaries.
Journal ArticleDOI
A front-tracking/front-capturing method for the simulation of 3D multi-fluid flows with free surfaces
F. S. de Sousa,Norberto Mangiavacchi,Luis Gustavo Nonato,A. Castelo,Murilo Francisco Tomé,Valdemir Garcia Ferreira,José Alberto Cuminato,Sean McKee +7 more
TL;DR: In this article, a method for simulating incompressible, imiscible, unsteady, Newtonian, multi-fluid flows with free surfaces is described, where a sharp interface separates fluids of different density and viscosity.
Journal ArticleDOI
GENSMAC3D: a numerical method for solving unsteady three‐dimensional free surface flows
Murilo Francisco Tomé,Antonio Castelo Filho,José Alberto Cuminato,Norberto Mangiavacchi,Sean McKee +4 more
TL;DR: In this article, a numerical method for solving three-dimensional free surface flows is presented, which is an extension of the GENSMAC code for calculating free surface flow in two dimensions.
