Book excerpt: An expression is given for the resistance of free surface flow in a porous medium, such as a rubble-mound breakwater, in terms of the density of the fluid, the approach velocity, the grain diameter of the material in the breakwater structure, and a resistance coefficient which is a function of Reynolds number of the flow. Tests indicated that the length of the structure relative to the grain diameter is an important factor in determining the resistance of free surface flow in a porous medium. A certain ratio between the length of the structure and its grain diameter must be reached before the structure can be treated as a porous medium. An expression derived by Dr. G.H. Keulegan for damping of translation waves by screen filters was modified to give the transmission coefficient of surface waves propagated through a porous structure. The constants in this expression were also found to be a function of the length of the structure relative to the grain diameter. Measured and computed values of wave transmission coefficients agreed well. (Author).

This book was released on 2002-05-30 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Abstract: In this thesis the simulation of the flow in alpha vertical permeable structure with alpha free surface is described. The underlying physical data had been achieved from experiments in a wave flume at the University of Cantabria. For the calibration of the numerical model COBRAS, a VOF type programme developed at Cornell University, the numerical results are compared with the laboratory data. The data analysed comes from 8 free surface sensors, placed inside and outside of the porous structure, and 4 pressure sensors, placed on the impermeable back wall inside the porous structure. An error analysis, using the least square technique, lead to a stepwise improvement of the numerical and the porous media parameters. In this process various grids had been tested, concerning sponge layer length, source function position and cell size. Later the porous media parameter for laminar and turbulent flow had been adjusted. For various wave conditions and porous structure characteristics, the optimal values for these parameters turned out to lay between 0 and 200 for alpha and between 0.45 and 0.8 for beta. The following error analysis yielded to alpha=100 and beta=0.5 usable for all tested wave and porous media characteristics.
