Twin Test 4 [TWT4] sessions has been completed at TU Delft
The second and final part of Twin Test 4 (TWT4) sessions has been completed at TU Delft .
An investigation of the scale effects on flow in the urban environment is carried out. More specifically, this urban environment is a series of five consecutive street canyons perpendicular to the approaching flow, simulating the urban fabric, since the street canyon geometry is usually considered as a fundamental component of contemporary cities. The examined canyon was the fourth one with respect to the direction of the approaching flow.
The effect of vegetation (hedges on the pedestrian level or roof greening) on the flow is also examined throughout this study.
The experiment at TU Delft was performed with a Volumetric PTV system, providing 3D measurements of the full velocity field (3 velocity components). Additionally, surface pressure measurements were conducted to supplement the PTV-extracted dataset.
