Laminar boundary layers over small-scale textured surfaces
Samuel D. Tomlinson, Demetrios T. Papageorgiou
We develop a model for steady, laminar boundary layers over small-scale textured surfaces. Although the texture is small relative to the boundary-layer thickness, it modifies the f…

Drag reduction in surfactant-contaminated superhydrophobic channels at high Péclet numbers
Samuel D. Tomlinson, Frédéric Gibou, Paolo Luzzatto-Fegiz +3
Motivated by microfluidic applications, we investigate drag reduction in laminar pressure-driven flows in channels with streamwise-periodic superhydrophobic surfaces (SHSs) contami…

Unsteady evolution of slip and drag in surfactant-contaminated superhydrophobic channels
Samuel D. Tomlinson, Frédéric Gibou, Paolo Luzzatto-Fegiz +3
Recognising that surfactants can impede the drag reduction resulting from superhydrophobic surfaces (SHSs), we investigate the impact of spatio-temporal fluctuations in surfactant…
