TL;DR: In this paper, the authors presented a simulation of the whole flow over a solid body covered by a porous layer and the three main models used in the literature to compute efficiently the fluid flow are given: the reduction of the porous layer to a boundary condition, the coupling of the Darcy equation with Navier-Stokes equations and the Brinkman-Navier-stokes equations or the penalisation method.

TL;DR: In this article, the passive control of bluff body flows using porous media is investigated by means of the penalization method, which is used to create intermediate porous media between solid obstacles and the fluid in order to modify the boundary layer behaviour.

TL;DR: It is shown that it is possible to couple passive and active control techniques to improve the flow control and a drag reduction of 30% is achieved, almost corresponding to the goal of automotive industry.

TL;DR: In this paper, the control of two-dimensional flows around the square back Ahmed body is achieved by using porous devices added on some parts of the body, where a good choice of the location of the porous interfaces yields a significant improvement of the aerodynamic quantities.

TL;DR: In this paper, a penalization method is discussed in the context of vortex methods for incompressible flows around complex geometries, in particular, the flow around a rotating======blade for Reynolds numbers 1000 and 10,000 and the flow past a semi-circular body consisting of a porous======layer surrounding a rigid body at Reynolds numbers 550 and 3000.
