Wind tunnel testing using reduced scale topography models is a mature technique [1] that enables the investigation of various aspects of wind flows from pollutant dispersion [2] to wind field modifications [3] affected by terrain. Alternatively, or in conjunction with a wind tunnel study, a rigorously developed computational technique would have the potential to provide additional and useful in...

A wind tunnel bioassay system to screen mosquito repellents is described. A wind tunnel is utilized to exploit the upwind flight response of host-seeking mosquitoes. Mosquitoes within the wind tunnel are activated with human breath, fly upwind, and land on heated chick skins. This behavioral sequence results in a consistently high percentage of the test population approaching repellent or contr...

Department of Aeronautical and Astronautical Engineering. University of Illinois at Urbana-Champaign. 306 Talbot Laboratory. 104 S. Wright Street. Urbana. IL 61801-2935 In a continuing effort to enhance the performance of small wind energy systems, one root airfoil and three primary airfoils were specifically designed for small horizontal axis wind turbines. These airfoils are intended primaril...

A wind tunnel conditions the air flow for testing equipment, such as heat exchangers, over a wide range of conditions. In this paper, a procedure to develop the operating envelope for the tested equipment in a wind tunnel is presented. The temperature and humidity of the air that requires conditioning is controlled and maintained by the combination of cooling coil (or evaporator), heating eleme...
