Higher-order homogenised riblet boundary conditions
Paolo Luchini, Daniel Chung
The description of riblets and other drag-reducing devices has long used the concept of longitudinal and transverse protrusion heights, both as a means to predict the drag reductio…

A simple and efficient second-order immersed-boundary method for the incompressible Navier--Stokes equations
Paolo Luchini, Davide Gatti, Alessandro Chiarini +3
An immersed-boundary method for the incompressible Navier--Stokes equations is presented. It employs discrete forcing for a sharp discrimination of the solid-fluid interface, and a…
