The presence of a porous layer at the surface of an immersed body modifies the nature of the flow at the solid-porous-fluid interface. This modification may lead to flow regularization and the use of porous coatings is considered as a passive flow control technique. However the understanding of the physical mechanisms responsible for such flow regularization with porous media is still incomplete. This work adresses the following questions : Is a porous layer able to delay the transition to a more turbulent flow regime ?
