The experimental databases provided on this page were obtained in wind tunnels of "Ecole Centrale de Lyon".
Flow and dispersion in streets-canyon
Description
These experiments describe the velocity fields (U, W), fluctuations of velocity and concentration in streets-canyon 2D, perpendicular to the direction of the wind outside.
Flow characteristics :
These experiments describe the velocity fields (U, W), fluctuations of velocity and concentration in streets-canyon 2D, perpendicular to the direction of the wind outside.
Flow characteristics :
- Aerodynamic roughness : 7,5E-5 m
- Friction velocity : 0,23 m/s
- Street square (H = W = 10cm) : Rue-carree.xls.
- Narrow street (H = 3 W = 20cm) : Rue-profonde.xls.
- Ascending street (H_amont = W = 10cm; H_aval = 2W = 20cm) : Rue-ascendante.xls.
- Down street (H_amont = 2W = 20cm; H_aval = W = 10cm) : Rue-descendante.xls.
