An equation for the volume average fluid velocity in a boundary layer region between a fluid and a porous medium is derived, The result is valid for a general anisotropic porous medium subject to the restrictions imposed by the assumptions made in the analysis. The basic equations of motion for an i
## Abstract Twoβdimensional numerical computation is performed for an unsteady laminar flow. Spatially the periodic boundary conditions are adopted in the streamwise direction and the adequacy of this treatment is studied by varying the computational domain size. The following results were obtained
A rectangular conduit with a closed end has water flowing in/out at the other end. The water level at the open end has an imposed sinusoidal movement. When this level is higher than the ceiling of the conduit, a certain mass of air is trapped under the ceiling. In a previous article (T.D. Nguyen, La
