The effect of discrete roughness elements on the development and breakdown of stationary
crossflow instability on a swept wing is explored. Receptivity to various element heights and …

In this work we apply a formulation for capturing detuned secondary instabilities. This
formulation, based on two-dimensional stability analysis coupled with a Bloch wave …

The presented work introduces a cancellation technique, based on the linear superposition
of stationary crossflow instabilities (CFIs) through the application of a streamwise series of …

The present work is dedicated to the investigation of the effect of an isolated roughness
element on a swept wing boundary layer. In particular, the flow modifications incurred by a …

Superhydrophobic surfaces dramatically reduce skin friction of overlying liquid flows. These
surfaces are complex and numerical simulations usually rely on models for reducing this …
