Experimental investigation on turbulent flow overlying permeable walls
A turbulent flow overlying a permeable wall can be subdivided into two distinct flow regions separated by a permeable interface. The first is the surface (or free) flow region, which overlies the interface. The second is the subsurface (or pore) flow region, which occurs within the permeable wall. …

PI2.0 : un-demolishing the projects
… Dwelling units and community amenities become a permeable wall that mediates relationships between the NGA campus and outside neighborhood as well as between the different groups living within the wall itself. With the looming ghost of modernist Pruitt-Igoe as its foil, PI2.0 abandons the …

Production of lactic acid by microbial fermentation of hemicellulose sugars
… (65 g) was packed in a fixed bed reactor with a permeable wall. The lactic acid productivity and yield in the novel bioreactor was higher than that of the control in both 20g/L and 50g/L xylose concentrations. The cells grew much quicker and better in the novel bioreactor than in the control. The …

Turbulent interactions between stream flow and near-subsurface flow: a laboratory approach using particle image velocimetry and refractive index matching
… flow around obstacles adjacent to a highly permeable wall. Supplementary experiments involving a mobile bed (D = 1.3 mm) in a very thin flume are also presented. With no obstacle on top of the bed, the mean velocity flow structure resembles that of a classic boundary layer, but with a …
