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…
Exogenous-endogenous surfactant interaction yields heterogeneous spreading in complex branching networks
Richard Mcnair, Fernando Temprano-Coleto, François J. Peaudecerf +4
Experiments have shown that surfactant introduced to a liquid-filled maze can find the solution path. We reveal how the maze-solving dynamics arise from interactions between the ad…
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…
Confinement-induced drift in Marangoni-driven transport of surfactant: a Lagrangian perspective
Richard Mcnair, Oliver E. Jensen, Julien R. Landel
Successive drops of coloured ink mixed with surfactant are deposited onto a thin film of water to create marbling patterns in the Japanese art technique of Suminagashi. To understa…
