(Received and accepted 27 April 1992)

The flow through permeable walls is studied for a variety of hole dimensions, spacings, and boundary conditions by the method of hydrodynamic cellular automata. The flux measured on the contact section of two adjacent channels is found to scale for all studied hole sizes from 1 to 128, regardless of whether the flow is forced by an imposed pressure difference between both channels or by the friction of the boundary layers in each of them.
