Shape optimization design of a heaving buoy of wave energy converter based on fully parametric modeling and CFD method
文献摘要：
The hydrodynamic shape of the heaving buoy is an important factor of the motion response in waves and thus concerns the energy conversion efficiency for the point absorbers (PAs). The current experience-based designs are time consuming and not very efficient, hence, faster and smarter methods are desirable. An automated optimization method based on a fully parametric modeling method and computational fluid dynamics (CFD), is proposed in this paper. Using this method, a benchmark buoy is screen designed and then optimized by maximizing the heave motion response. The geometry is described parametrically and deformed by means of the free-form deformation (FFD) method. During the optimization process, the expansion factor of control points is the basis for the variations. A combination of the Sobol and the non-dominated sorting genetic algorithm Ⅱ(NSGA-II) is used to search for the solutions. After several iterations, the heaving buoy shape with optimal heave motion response is obtained. The analyses show that the heave motion response has increased 55.3％ after optimization. The developed methodology is valid and seems to be a promising way to design a novel buoy that can significantly improve the wave energy conversion efficiency of the PAs in future.
