Permeability and turbulence over perforated plates

HIGHLIGHTS

• who: Haris Shahzad from the Aerodynamics Group, Faculty of Aerospace Engineering, Delft University of Technology, Kluyverweg, HS Delft, South Holland, The Netherlands have published the research work: Permeability and Turbulence Over Perforated Plates, in the Journal: (JOURNAL)
• what: The authors find evidence of a fully rough regime where the relevant length scale is the inverse of the Forchheimer coefficient which can be regarded as the resistance experienced by the wall-normal Moreover the authors show that for low porosities the Forchheimer coefficient can be estimated with good accuracy using a simple analytical relation. The authors . . .
