Flow structures and transport: predictability and control

移动的流动结构（涡流的边界，两种流体之间的流动界面）在流体混合和热量、污染物和营养物质的输送中至关重要。这个项目将分析它们在改进地球物理尺度问题扩散程度和速率的预测方面的作用，以及在控制微观尺度的传输方面的作用。将通过与最近的精确模型进行比较，全面评估目前可用的输运预测数值诊断的不准确性。将发展非定常流动协议下定量输运的分析方法，并与实验人员一起回答微流体应用中控制输运的问题。

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.
