Flow over and past porous surfaces

Autor: Showkat Ali, Syamir Alihan

This thesis is concerned with the application of porous treatments as a means of flow and aerodynamic noise reduction. An extensive experimental investigation is undertaken to study the effects of flow interaction with porous media, in particular in
