- 요약This dissertation investigates particle capture in a model chaotic flow, with motivation from geophysical applications such as pollutant removal from oceans and the atmosphere. Utilizing the double-gyre model, a chaotic flow sharing similarities with geophysical systems, the study examines both stationary and mobile capture units to understand their effectiveness in various chaotic environments.The research begins by exploring stationary capture units, where the effectiveness of particle capture is analyzed in relation to the location within chaotic and non-chaotic regions of the flow. A novel numerical approach is developed to identify and characterize flow structures, particularly barriers to transport, which play a crucial role in determining capture efficiency. The findings highlight that capture efficiency is strongly influenced by the presence of these barriers, with units placed in chaotic/non-chaotic regions showing the highest capture capability.Building on these insights, the study extends to mobile capture units, which are more practical for dynamic environments. Various movement strategies for mobile units are explored, evaluating their performance under different flow conditions. The results reveal that adaptive strategies that account for the underlying chaotic structures of the flow can dramatically improve capture efficiency.Finally, a comprehensive scaling analysis is conducted to establish a relationship between flow parameters, capture unit characteristics, and capture efficiency. This analysis provides a framework for optimizing the design and operation of pollutant capture systems in real-world chaotic fluid environments.
