Wind turbine wakes on escarpments: A wind-tunnel study

Fernando Porté Agel, Arslan Salim Dar

In this study, the wake behind a wind turbine located on an escarpment is investigated using particle-image velocimetry in a wind tunnel. Five different escarpment models are used, which vary in the windward side shape from forward facing steps (FFS) with ...

An experimental investigation of a roof-mounted horizontal-axis wind turbine in an idealized urban environment

Fernando Porté Agel, Arslan Salim Dar, Guillem Armengol Barcos

Wind-tunnel experiments are performed to investigate the effect of minor modifications to the roof edge shape on the power performance and wake characteristics of a horizontal-axis wind turbine sited on a cube-shaped building. Three roof edge shapes are co ...
