This project investigates the fundamental fluid mechanics of particle capture, whereby suspended particles contact and adhere to a solid structure. This process is examined in productive and biodiverse ecosystems (such as coral reefs and seagrass meadows) whose health, productivity and propagation are directly controlled by particle capture. Existing formulations for particle capture are valid only under highly idealised conditions that are grossly unrepresentative of the complexity of ecosystem flows. The goal of this project is to use a coupled computational-experimental campaign to develop predictive capability for particle capture in ecosystems, where the flow can be turbulent and/or wave-dominated and the biological structures complex.

该项目研究颗粒捕获的基本流体力学，即悬浮颗粒接触并粘附在固体结构上。这一过程在生产性和生物多样性生态系统（如珊瑚礁和海草草甸）中进行了研究，这些生态系统的健康、生产力和繁殖直接受颗粒捕获的控制。现有的配方颗粒捕获是有效的，只有在高度理想化的条件下，是严重不代表生态系统流的复杂性。该项目的目标是使用一个耦合的计算实验活动，以发展预测能力的颗粒捕获在生态系统中，其中的流动可以是湍流和/或波为主的生物结构复杂。
