Prediction of resistance induced by surface complexity in lubricating layers: Application to super-hydrophobic surfaces
Noura Bettaieb, Marco Castagana, Pierre-Yves Passaggia +2
Super Hydrophobic (SH) coatings are widely used to mitigate drag in various applications. Numerous studies have demonstrated that the beneficial wall-slip effect produced by these…
Limiting regimes of turbulent horizontal convection. Part II : Large Prandtl numbers
Pierre-Yves Passaggia, Nadia F. Cohen, Alberto Scotti +1
Horizontal Convection (HC) at large Rayleigh and Prandtl numbers, is studied experimentally in a regime up to seven orders of magnitude larger in terms of Rayleigh numbers than pre…
Limiting regimes of turbulent horizontal convection. Part I: Intermediate and low Prandtl numbers
Pierre-Yves Passaggia, Alberto Scotti, Brian L. White
We report the existence of two new limiting turbulent regimes in horizontal convection (HC) using direct numerical simulations at intermediate to low Prandtl numbers. The flow driv…
Transient energy growth in the ageostrophic Eady model
Varvara E. Zemskova, Pierre-Yves Passaggia, Brian L. White
The problem of optimal initial disturbances in thermal wind shear is revisited and extended to include non-hydrostatic effects. This systematic study compares transient and modal g…
An Isotropic Porous Medium Approach to Drag Mitigation Disappearance in Super-Hydrophobic Falling Spheres
Marco Castagna, Nicolas Mazellier, Pierre-Yves Passaggia +1
In this Letter, the falling of super-hydrophobic spheres is investigated experimentally at low Reynolds numbers. In particular, we show that super-hydrophobic coatings become ineff…
Heat and momentum transport in turbulent horizontal convection at low Prandtl numbers
Pierre-Yves Passaggia, Alberto Scotti, Brian L. White
The transition to a new turbulent regime in horizontal convection in the case of low Prandtl numbers is analyzed using the Shishkina, Grossmann & Lohse (SGL) theory. The flow drive…
