Moving flow structures (the boundary of an eddy, the flow interface between two fluids) are crucial in fluid mixing and in the transport of heat, pollutants and nutrients. This project will analyse their roles in improving predictions of spreading extents and rates for geophysical-scale problems, and in controlling transport at the micro-scale. Inaccuracies in currently available numerical diagnostics for transport prediction will be comprehensively evaluated via comparison with recent exact models. Analytical methods for quantifying transport under unsteady flow protocols will be developed, and used to answer questions on controlling transport in microfluidic applications in conjunction with experimentalists.

移动的流动结构（涡流的边界，两种流体之间的流动界面）在流体混合以及热量，污染物和营养物的传输中至关重要。该项目将分析它们在改进对空间尺度问题的扩散范围和速度的预测以及在控制微观尺度的运输方面的作用。通过与最近的精确模型进行比较，将全面评估目前可用的数值诊断运输预测的不准确性。将开发用于在不稳定流协议下定量运输的分析方法，并用于回答与实验人员一起控制微流体应用中运输的问题。
