Hypolimnetic Oxygenation: Coupling Bubble-Plume and Reservoir Models

0202034将确定气泡羽流在水中诱导的混合机制，并将其纳入用于亚磁供氧系统设计和操作的耦合气泡羽流水库模型中。现场测试将使用弗吉尼亚州一个小型供水水库中的线性气泡羽流扩散器和瑞士一个中型富营养化湖泊中的六个圆形气泡羽流扩散器。在扩散器运行之前、期间和之后，将监测氧气转移和羽流诱导的混合。此外，还将监测生物地球化学通量。这项研究将使第一个科学严谨的气泡-羽流/二维水库耦合模型的开发成为可能，该模型包括氧转移、羽流诱导的混合以及对生物地球化学通量的影响，包括超氧化物歧化酶。

0202034 Little The mixing mechanisms induced in water by bubble-plumes will be identified and incorporated into a coupled bubble-plume reservoir model for design and operation of hypolimnetic oxygenation systems.Field testing will be conducted using a linear bubble-plume diffuser in a small water supply reservoir in Virginia and using six circular bubble-plume diffusers in a mid-sized eutrophic lake in Switzerland. Oxygen transfer and plume induced mixing will be monitored before, during and after diffuser operation. In addition, biogeochemical fluxes will be monitored.This research will enable the development of the first scientifically rigorous coupled bubble-plume/ two dimensional reservoir model that includes mechanistic features of oxygen transfer, plume-induced mixing and the impact on biogeochemical fluxes, including SOD.
