Integral relations for the skin-friction coefficients and other quantities of annular flows
Pierre Ricco
Integral identities relating the skin-friction coefficients and the Reynolds shear stresses in annular cylindrical flows are derived. In the pressure-driven case, an identity for t…
Turbulent boundary layers altered by passively rotating discs
Max W. Knoop, Pierre Ricco
The study experimentally investigates how flush‑mounted, passively rotating discs affect turbulent boundary‑layer skin‑friction drag in a wind tunnel, finding a modest 3% drag redu…
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 FossÃ, 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 d…
