项目摘要

Mixing processes in water bodies involves various phenomena at small and large scales. At "small" scales such as outfalls, rotation effects are not significant while at large scales they are important. At large scales such as "Great Lakes" and oceanic problems, Coriolis effect can play an important role. Numerical simulation of mixing processes is a challenging issue, both from numerical aspects and from modelling strategies. It is in the best interest of the numerical modelling community to obtain faster and more accurate methods to improve simulations. The proposed research program is aimed at the development of accurate and efficient tools for simulating flow and mixing processes in water resources, based on the applicant's background in high-performance computing and fluid mechanics. In this research, the new, highly accurate temporal and spatial numerical methods recently proposed by the applicant for free surface flows will be extended to simulate mixing processes in three dimensions. Moreover, recent developments by the applicant in modeling turbulent buoyant outfalls will be expanded to more practical cases and the impact of free surface processes such as waves on mixing will be further examined. At larger scales, interaction of waves and turbulence occurs under the Coriolis effect, which is not yet well understood. Correct modelling of these interactions is crucial for ocean modelling and simulation of climate changes. The emergence of large-scale flows such as oceanic jets from small-scale turbulence has been also studied by the applicant, and appropriate numerical methods have been also proposed, which will be further expanded and studied in this research program.**
水体中的混合过程涉及在大小尺度上的各种现象。在“小”量表(例如排放量)下,旋转效应并不重要,而在大尺度上它们很重要。在大规模的“大湖区”和海洋问题,科里奥利效应可以发挥重要作用。从数值方面和建模策略来看,混合过程的数值模拟是一个具有挑战性的问题。数值建模社区的最大利益是获得更快,更准确的方法来改善模拟的方法。拟议的研究计划旨在开发基于申请人高性能计算和流体力学的背景,以开发水资源中的流动和混合过程的准确有效工具。在这项研究中,申请人最近提出的新型,高度准确的时间和空间数值方法将扩展以在三个维度上模拟混合过程。此外,申请人在建模湍流浮力排放量进行建模的最新发展将扩展到更实际的情况,并且将进一步研究自由表面过程(例如波浪)的影响。在较大的尺度下,波和湍流的相互作用发生在科里奥利效应下,尚未得到充分理解。这些相互作用的正确建模对于海洋建模和气候变化的模拟至关重要。申请人还研究了大规模湍流中的大规模流量,例如来自小规模湍流的海洋喷气机,并且还提出了适当的数值方法,该方法将在该研究计划中进一步扩展和研究。** **
