Simulation of atmospheric boundary layer for full- and large- scale experiments in large wind tunnels
Dejiang Chen, Arindam Chowdhury, Ioannis Zisis and Amal Elawady

 
Abstract
     The primary objective of this paper is to present the current capabilities for simulating atmospheric boundary layer (ABL) flows in large-scale wind tunnels. The paper describes (i) methods for generating ABL flow conditions appropriate for full- and large-scale experimental investigations, and (ii) the resulting flow characteristics obtained using these methods. The Florida International University Wall of Wind Experimental Facility (WOW EF) and associated experimental and analytical techniques used to simulate ABL flows are described. Resulting ABL flow simulations at various model scales are compared to their Engineering Sciences Data Unit (ESDU) counterparts. Additionally, aerodynamic pressure measurements from WOW models of the Wind Engineering Research Field Laboratory (WERFL) building at Texas Tech University (TTU) are compared with full-scale field measurements recorded on the TTU prototype. The results of the comparisons, and uncertainties in the simulated and field measured data are discussed, and suggestions are presented on future research needs.
