英文摘要： This project focuses on the layout optimization of horizontal ocean current turbine (HOCT) arrays. With a combined method of both theoretic analysis and experimental test, the wake structure of HOCTs will be studied in depth, and the effect of turbine array configurations on the turbines’ hydrodynamic performance will be studied as well. The main content and innovations of this project are summarized as follows. Firstly, based on the actuated disk model, an analytical model that precisely characterizes the wake behind a single HOCT and the interaction stream between multi HOCTs will be developed. The distribution of pressure, velocity, and turbulence intensity of the turbine field will be analyzed under different array configurations. Secondly, concerning the optimization of turbines array configurations, the characterization parameter and the relationship model will be studied. The influence of array configurationsof turbines on the wake structure of the turbine farm will be studied.
