Upper bounds on the colloid separation efficiency of diffusiophoresis
Fernando Temprano-Coleto, Jeongmin Kim, Marcel M. Louis +1
The separation of colloidal particles from fluids is essential to ensure a safe global supply of drinking water, yet in the case of microscopic particles, it remains a highly energ…
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…
On the self-similarity of unbounded viscous Marangoni flows
Fernando Temprano-Coleto, Howard A. Stone
The Marangoni flow induced by an insoluble surfactant on a fluid-fluid interface is a fundamental problem investigated extensively due to its implications in colloid science, biolo…
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…
A model for slip and drag in turbulent flows over superhydrophobic surfaces with surfactant
Samuel D. Tomlinson, François Peaudecerf, Fernando Temprano-Coleto +4
Superhydrophobic surfaces (SHSs) can reduce the friction drag in turbulent flows. In the laminar regime, it has been shown that trace amounts of surfactant can negate this drag red…
Laminar drag reduction in surfactant-contaminated superhydrophobic channels
Samuel D. Tomlinson, Frédéric Gibou, Paolo Luzzatto-Fegiz +3
While superhydrophobic surfaces (SHSs) show promise for drag reduction applications, their performance can be compromised by traces of surfactant, which generate Marangoni stresses…
A single parameter can predict surfactant impairment of superhydrophobic drag reduction
Fernando Temprano-Coleto, Scott M. Smith, François J. Peaudecerf +3
Recent experimental and computational investigations have shown that trace amounts of surfactants, unavoidable in practice, can critically impair the drag reduction of superhydroph…
A theory for the slip and drag of superhydrophobic surfaces with surfactant
Julien R. Landel, François J. Peaudecerf, Fernando Temprano-Coleto +3
Superhydrophobic surfaces (SHSs) have the potential to reduce drag at solid boundaries. However, multiple independent studies have recently shown that small amounts of surfactant,…
