This Thesis deals with turbulent flows, mostly wall-bounded flows, with a special focus on skin-friction drag reduction. It takes a global stance at the topic, by making new attempts to understand the elusive physics behind drag reduction with novel methods, and by addressing some of the many practical obstacles that still prevent drag reduction techniques to be deployed in applications.
Questa Tesi si occupa della riduzione della resistenza di attrito viscoso in correnti turbolente confinate tra pareti. La Tesi affronta l'argomento in modo globale, compiendo nuovi tentativi di comprendere i meccanismi fisici alla base della riduzione di resistenza con metodi innovativi e affrontando alcuni dei numerosi ostacoli pratici che ancora impediscono alle tecniche di riduzione di resistenza di essere impiegate in applicazioni reali.

Abstract
This Thesis deals with turbulent flows, mostly wall-bounded flows, with a special focus on skin-friction drag reduction. It takes a global stance at the topic, by making new attempts to understand the elusive physics behind drag reduction with novel methods, and by addressing some of the many practical obstacles that still prevent drag reduction techniques to be deployed in applications.File | Dimensione | Formato | |
