项目摘要
This award is to support research to improve understanding of air-water mass transfer. The liquid film coefficient relates to low solubility and relatively unreactive compounds where air-water transfer is controlled by the water phase or by both phases, such as O2, N2, CO2, DDT, most PCB's, and several mercury compounds. The coefficient describes the resistance to transfer in the liquid phase. A unique flume has been designed and built to study water-phase controlled mass transfer on the scale of a laboratory flume, while maintaining the measurement accuracy of a contained tank or laboratory beaker. The most fundamental objective of this research is to determine the basic mechanism by which a flowing open channel interacts with the free water surface to reduce the liquid film coefficient. The results are expected to provide a basis for the evaluation of existing natural stream data and to specify the important parameters to be measured when determining the liquid film coefficient in natural streams. The principal investigator is highly qualified to carryout the proposed research. A two year continuing grant is recommended. This award is for $75,827 for the first year.
该奖项是为了支持提高对空气-水传质的理解的研究。液膜系数与低溶解度和相对不反应的化合物有关,其中空气-水传递由水相或由两相控制,如O2、N2、CO2、DDT、大多数多氯联苯和几种汞化合物。该系数描述了液体中的传递阻力。设计和建造了一种独特的水槽,用于在实验室水槽规模上研究水相控制传质,同时保持密封罐或实验室烧杯的测量精度。这项研究最基本的目的是确定流动明渠与自由水面相互作用以降低液膜系数的基本机理。研究结果可望为评价现有的天然水流数据提供依据,并明确在测定天然水流中的液膜系数时需要测量的重要参数。首席调查员非常有资格进行拟议中的研究。建议提供为期两年的持续资助。该奖项的第一年奖金为75,827美元。
