Turbulent Drag Reduction Using Anisotropic Permeable Substrates.

G Gómez-de-Segura, A Sharma, R García-Mayoral

Jul 18, 2018

The behaviour of turbulent flow over anisotropic permeable substrates is studied using linear stability analysis and direct numerical simulations (DNS). The flow within the permeable substrate is modelled using the Brinkman...

Spectral Analysis of the Slip-Length Model for Turbulence over Textured Superhydrophobic Surfaces.

CT Fairhall, R García-Mayoral

Jul 12, 2018

We assess the applicability of slip-length models to represent textured superhydrophobic surfaces. From the results of direct numerical simulations, and by considering the slip length from a spectral perspective, we discriminate...
