In the porous-media approach, the porous or perforated structure is represented by its volume-averaged properties via a geometrically defined porous region of volumetric dimension. In this continuous and homogeneous porous region, resistance source terms are applied as closure terms to the … See more In the present context of wave interaction with thin perforated sheets and cylinders, two main flow scales are of interest, the flow through the sheet openings on a small scale, and the … See more The pressure-drop, \Delta p, across a porous barrier can be written as a function of the flow velocity (usually formulated with the Darcy-velocity \varvec{U}): where a, C_\mathrm{{f}} and c are porosity or pressure-drop … See more For the wave modelling, OlaFlow provides wave generation boundary conditions and an active wave absorption treatment based on common potential-flow wave theories. The active wave absorption method (AWA) … See more WebTheory. Low Reynolds number fluid flow in a porous medium is described by Darcy’s law, (1)→v = − K μϵ→∇p. where, →v is the fluid velocity, K is the matrix permeability, μ is the …
