A fluorometer for measuring mixing and discharge in urban and aquatic environments

需要资金购买便携式荧光计，用于测量城市和水环境中荧光染料的浓度。荧光计可以准确地测量染料浓度。通过监测染料注入水体后的浓度，可以得到混合和稀释的速度。此外，通过测量完全混合后注入的染料的相对浓度，可以准确地测量城市系统中的废水排放量。拟议的荧光计将支持朱博士、N·拉贾拉特南博士和P·斯特夫勒博士在湍流射流动力学、河流和湖泊中的污水混合、城市系统的水力学以及水生系统中的水质建模和管理方面的研究项目。

Funds are requested to purchase a portable fluorometer for measuring the concentration of a fluorescent dye in urban and aquatic environments. A fluorometer provides accurate measurement of dye concentration. By monitoring the dye concentration after its injection in a water body, the rate of mixing and dilution can be obtained. In addition, by measuring the relative concentration of the injected dye after it is fully mixed, discharges of wastewater in urban systems can be accurately measured. The proposed fluorometer will support the research programs of Dr. D. Zhu, Dr. N. Rajaratnam and Dr. P. Steffler on the dynamics of turbulent jets, effluent mixing in rivers and lakes, hydraulics of urban systems, and modeling and management of water quality in aquatic systems.
