9908145LittleThis one-year award for an U.S.-Swiss research project in environmental technology supports Dr. John C. Little and a graduate student from Virginia Polytechnic Institute and State University for collaboration with Dr. Alfred J. Wuest, head of the Environmental Physic Program at the Federal Institute for Technology in Zurich, Switzerland. The project addresses the impact of bubble-plume diffusers on a water-supply reservoir. Bubble-plume diffusers are used to replenish oxygen in the hypolimnion of stratified reservoirs. These devices are required to preserve cold-water fisheries, improve raw water quality in water-supply reservoirs, and mitigate environmental consequences of hydropower generation. Evidence indicates that bubble-plume diffusers can have a significant impact on ambient conditions within a reservoir (promoting mixing and enhancing sediment oxygen demand), and that conditions within a reservoir can in turn have a severe impact on the performance of a bubble-plume. The investigators propose to develop an integrated model in which the behavior of both bubble-plume diffusers and the reservoir are coupled. This collaboration takes advantage of the complementary expertise of the U.S. investigator in cross-media mass transfer and the Swiss investigator's in bubble-plume modeling and aeration technology.

9908145授予美国环境技术研究项目的一年奖，支持John C. Little博士，以及弗吉尼亚理工学院和州大学的研究生，与瑞士Zurich联邦技术研究所的环境物理学计划主管Alfred J. Wuest博士合作。 该项目涉及气泡 - 胶合物扩散器对水供应水库的影响。 气泡液扩散器用于在分层储层中降解中补充氧气。 这些设备需要保存冷水渔业，改善水供应水库的原始水质以及减轻水力发电的环境后果。 证据表明，气泡 - 泵扩散器可能会对储层内的环境条件产生重大影响（促进混合和增强沉积物氧的需求），而储层中的条件反过来又对泡泡胶的性能产生了严重影响。 研究人员建议开发一个综合模型，在该模型中，耦合了气泡泵扩散器和储层的行为。 这项合作利用了美国调查员在跨媒体传播和瑞士调查员泡泡式建模和曝气技术方面的补充专业知识。
