U.S.-Uruguay Cooperative Research: Comparative Studies in Two Boundary Layer Wind Tunnels

小行星9601420 该美洲计划奖将支持明尼苏达大学的塞萨尔法雷尔博士和乌拉圭蒙得维的亚大学流体和环境工程机械研究所（IMFIA）的拉斐尔·瓜尔加博士之间的合作研究项目。 目的是对两个附面层风洞的性能进行比较研究，一个在蒙得维的亚，由IMFIA指导，另一个在明尼苏达州圣安东尼福尔斯实验室（SAFL）。 拟议的计划将提供几个隧道组件的原型性能数据。 将比较两个隧道中大气边界层的模拟，注意湍流及其尺度对建筑物模型上的平均压力和波动压力的影响。 在大气边界层模拟的关键问题的研究中已经取得了相当大的进展，但仍有许多方面的技术需要调查。 这项研究的结果补充了早期NSF资助的与SAFL隧道的设计和评估相关的工作，将有助于更好地理解流动动力学和识别基本建模要求。 对美国研究工作的好处将是增加人力，扩大工作范围，包括不同的部件几何形状和规模，并有机会促进科学知识的国际交流。 ***

9601420 Farell This Americas Program award will support a collaborative research project between Dr. Cesar Farell, University of Minnesota, and Dr. Rafael Guarga, Instituto de Mecanica de los Fluidos e Ingenieria Ambiental, Universidad de la Republica, Montevideo, Uruguay (IMFIA). The objective is to carry out comparative studies of the performance of two boundary layer wind tunnels, one in Montevideo, under the direction of IMFIA and the other at the St. Anthony Falls Laboratory (SAFL), Minnesota. The proposed program will provide prototype performance data for several of the tunnel components. Simulations of atmospheric boundary layers in both tunnels would be compared, with attention to the effects of turbulence and its scales on the mean and fluctuating pressures on building models. Considerable advances have been made in ongoing research to investigate critical issues in the modeling of atmospheric boundary layers, but there are many aspects of the techniques that still require investigation. Results of this research, which complements earlier NSF funded work related to the design and evaluation of the SAFL tunnel, would make a contribution toward a better understanding of the flow dynamics and the identification of essential modeling requirements. The benefit to the U.S. research effort will be in added manpower, and broadened scope of work to include different component geometries and scales, and the opportunity to advance the international exchange of scientific knowledge. ***
