Transient and periodic shear wave propagation in a solid-fluid coupled system
Aaron D'Cruz, Pierre Ricco
A coupled system composed of a Newtonian fluid located on a sinusoidally-forced elastic solid is studied analytically and numerically. The focus is on the transient evolution from…
Compressible boundary layers over isotropic porous surfaces
Ludovico Fossà, Pierre Ricco
A compressible laminar boundary layer developing over an isotropic porous substrate is investigated by asymptotic and numerical methods. The substrate is modeled as an array of cub…
Excitation and stability of nonlinear compressible Görtler vortices and streaks induced by free-stream vortical disturbances
Dongdong Xu, Pierre Ricco, Elena Marensi
We study the generation, nonlinear development and secondary instability of unsteady Görtler vortices and streaks in compressible boundary layers exposed to free-stream vortical di…
Separation drag reduction through a spanwise oscillating pressure gradient
Vinh-Tan Nguyen, Pierre Ricco, Gianluca Pironti
An oscillating spanwise pressure gradient is imposed numerically to control the flow separation and reduce the drag of a turbulent flow in a channel with square bars. The transvers…
Wall-oscillation conditions for drag reduction in turbulent channel flow
Pierre Ricco, Maurizio Quadrio
The drag reduction properties of a turbulent channel flow modified by spanwise sinusoidal oscillations of the walls are investigated by direct numerical simulations. The work is ba…
