Abstract

An approach to describe the turbulent flow through a complex geometry (e.g. urban area) by means of an analogy to flows through porous media is presented. Therefore, a modification of the original Darcy's law is proposed and its application is tested in a prototype problem with an idealized complex geometry using large-eddy simulations. The numerical results indicate the validity of the modified Darcy's law for the chosen setup.
