Aerodynamic Characteristics of Boundary Layer Wind Tunnel and Design of Tunnel Components

该奖项支持明尼苏达大学的Cesar Farell和乌拉圭蒙得维的亚共和国大学的Raphael Guarga在空气动力学方面的合作研究。他们将研究风洞边界层的气动特性和风洞设计的各个方面。明尼苏达州的水力实验室和蒙得维的亚的工程学院都建造了大气风洞。开展开合回路隧道构件的基础设计研究。入口、扩散器及其对流动质量的影响将与使用压力管、风速测量和流动可视化的湍流管理一起进行研究。来自两条隧道的数据将与现有的结构空气动力学模型、节能模型和对行人的影响模型进行比较。乌拉圭风洞研究和风力工程的发展将受益于这项工作，培训和使用科学家和工程师的能力也将受益于这项工作。美国将通过增加人力和扩大不同部件几何形状和规模的工作范围而受益。这样，双方互利共赢的SDC项目目标将得以实现。

This award supports cooperative research in aerodynamics by Cesar Farell of the University of Minnesota and Raphael Guarga of the University of the Republic in Montevideo, Uruguay. They will study the aerodynamic characteristics of boundary layers in wind tunnels and various aspects of tunnel design. Atmospheric wind tunnels have been built in both the Hydraulic Laboratory in Minnesota and at the School of Engineering in Montevideo. Basic design research will be carried out on components of open and closed circuit tunnels. Inlets, diffusers and their effect on flow quality will be investigated along with turbulence management using pressure tubes, anemometry and flow visualization. Data from both tunnels will be compared with current models of the aerodynamics of structures, energy conservation and effect on pedestrians. The growth of wind tunnel research and wind engineering in Uruguay will benefit from this work as will the capacity to train and use scientists and engineers. The U.S. will benefit through added manpower and a broadened work scope of different component geometries and scales. Thus the goal of the SDC program of mutual benefit to both will be fulfilled.
