摘要

建立并实现了一种计算流体力学方法,作为螺旋螺旋桨推进对水平轴水轮机可再生能源性能预测、设计和优化的工具。以潮汐能发电为例,从几何参数、运动参数、入流速度分析和实现方法等方面对螺旋螺旋桨与水平轴水轮机进行了对比分析。对船舶螺旋桨模型和已有实验测量的水平轴涡轮模型进行了比较和分析。从推力系数、轴转矩/功率系数、叶片表面压力分布和下游速度分布等方面进行了分析和比较。计算并给出了2 ~ 5片叶片数对潮汐水轮机水动力效率的影响。详细介绍了该面板法作为水平轴涡轮机预测工具的关键实现技术和方法。虽然该方法在过去的许多螺旋桨测试中已被证明是准确和稳健的,但该数值工具也被验证并用于潮汐和风力涡轮机。

A panel method for both marine propulsion and renewable energy
A computational hydrodynamics method was formulated and implemented as a tool from screw propeller propulsion to renewable energy performance prediction, design and optimization of horizontal axis turbines. As an example for tidal energy generation, a comparative analysis between screw propellers and horizontal axis turbines was presented, in terms of geometry and motion parameters, inflow velocity analysis and the implementation methodologies. Comparison and analysis are given for a marine propeller model and a horizontal axis turbine model that have experimental measurements available in literature. Analysis and comparison are presented in terms of thrust coefficients, shaft torque/power coefficients, blade surface pressure distributions, and downstream velocity profiles. The effect of number of blades from 2 to 5, of a tidal turbine on hydrodynamic efficiency is also obtained and presented. The key implementation techniques and methodologies are provided in detail for this panel method as a prediction tool for horizontal axis turbines. While the method has been proven to be accurate and robust for many propellers tested in the past, this numerical tool was also validated and presented for both tidal and wind turbines.

期刊介绍: TJPRC: Journal of Naval Architecture and Marine Engineering (JNAME) is a peer reviewed journal and it provides a forum for engineers and scientists from a wide range of disciplines to present and discuss various phenomena in the utilization and preservation of ocean environment. Without being limited by the traditional categorization, it is encouraged to present advanced technology development and scientific research, as long as they are aimed for more and better human engagement with ocean environment. Topics include, but not limited to: marine hydrodynamics; structural mechanics; marine propulsion system; design methodology & practice; production technology; system dynamics & control; marine equipment technology; materials science; under-water acoustics; satellite observations; and information technology related to ship and marine systems; ocean energy systems; marine environmental engineering; maritime safety engineering; polar & arctic engineering; coastal & port engineering; aqua-cultural engineering; sub-sea engineering; and specialized water-craft engineering. International Journal of Naval Architecture and Ocean Engineering is published quarterly by the Society of Naval Architects of Korea. In addition to original, full-length, refereed papers, review articles by leading authorities and articulated technical discussions of highly technical interest are also published.
