| Summary: | The purpose of this paper is to describe an attempt made to simulate the atmospheric
boundary layer (ABL) in the Low Speed Wind Tunnel (LSWT) at IIUM. This was performed
through modifications of the inlet and surface conditions of the test section. Devices such as
spires, fences and surface roughness were used. The ASCE 7-10 standard was used as a
reference to validate the results between the wind tunnel data and the full-scale ABL flow
characteristics. The velocity profile and turbulence intensity were measured using a onedimensional
hotwire (CTA) probe. The data obtained show good agreement with ASCE 7-10
velocity profiles for exposures B and C while using a scale of 1:488 to match the wind tunnel
data. The turbulence intensity profiles do not show a good agreement. |
