This project aims to capture conditions responsible for the generation of the coherent structures that are formed in wall-bounded turbulent flows, through the use of variational data assimilation and adjoint-based optimisation techniques. The project is expected to provide knowledge and intellectual property that is essential for the accurate modelling and prediction of the interaction between the ground-level activities like pollutant emissions and the atmosphere and the flow over vehicles through pipes, turbines and compressors. This project will provide benefits such as reducing the risk in environmental and commercial design and decision making and will facilitate new opportunities for the commercial development of devices to reduce drag and enhance mixing and heat transfer via the direct manipulation of coherent structures.

该项目旨在通过使用变分数据同化和基于伴随的优化技术来捕获在壁界湍流中形成的相干结构的生成条件。该项目预计将提供知识和知识产权，这对于准确建模和预测污染物排放与大气等地面活动以及通过管道、涡轮机和压缩机流过车辆的流量之间的相互作用至关重要。该项目将提供诸如降低环境和商业设计和决策风险等好处，并将为设备的商业开发提供新的机会，以通过直接操纵相干结构来减少阻力并增强混合和传热。
