吃水深度对振荡水柱式波浪能发电浮标水动力学性能的影响
Study on the influence of draft on hydrodynamic performance of oscillating water column wave power buoy
摘要
Abstract
The energy conversion efficiency of wave energy buoys is determined by their hydrodynamic performance.From design experience,it is known that the hydrodynamic performance of buoys is greatly affected by the draft depth.The article takes wave energy buoys as the research object and conducts a study on the hydrodynamic performance of buoy draft depth.Firstly,introduce the structure and working principle of the buoy;Secondly,establish simulation models of the buoy under five different draft depth conditions,conduct numerical simulation calculations,and obtain the hydrodynamic parameters and energy conversion efficiency of the buoy under design conditions;Finally,physical model experiments were conducted to study the capture width ratio(RCW)of buoys under six different draft conditions,and compared and analyzed with simulation results.The results show that when the draft depth is 75 mm,the maximum RCW of the model is 56.8%;the draft depth has a significant impact on the peak distribution of buoy RCW;under specific aerodynamic damping,the simulation results fit well with the physical model test results,with an error of less than 5% .关键词
