In this work a penalization method is discussed in the context of vortex methods for incompressible flows around complex geometries. In particular we illustrate the method in two cases : the flow around a rotating blade for Reynolds Numbers 1000 and 10000 and the flow past a semi-circular body consisting of a porous layer surrounding a rigid body at Reynolds numbers 550 and 3000. In the latter example, the results are interpreted in terms of control strategy.
