摘要
为分析翼面效应对并联振荡水翼获能功率的影响,基于重叠网格技术建立了水翼并联运动的数值模型,并进行了有效性验证。利用所建的数值模型针对小间距下双水翼的水动力性能进行了分析,研究了翼间距对双翼翼面效应(wing-in-surface-effect)的影响;并根据翼面效应的增益效果,进一步研究了三水翼运动的复杂问题,并计算了其平均功率系数。研究结果表明:减小水翼最小间距会增强翼面效应;双翼系统的平均功率系数会随着水翼间最小间距的减小而增大;三翼系统的平均功率系数大于双翼系统。通过以上研究可知:翼面效应会提高水翼的平均功率系数,水翼个数的增加会提高水翼的平均功率系数。
To study the influence of wing-in-surface-effect(WISE)on the hydrodynamic performance of hydrofoil,a numerical model was established based on overset grid method with the convergence study.Based on this numerical model,the hydrodynamic performance of two hydrofoils with different minimum distance was studied.To amplify the WISE,a power generation with three hydrofoilswas proposed and its power coefficient was calculated.The results show that:the decrease of the minimum spacing between hydrofoils enhances the WISE;the power coefficient of the two hydrofoils system increases with the decrease of the minimum spacing between hydrofoils;the power coefficient of the three hydrofoils system is greater than that of the two hydrofoils system.The WISE can improve the power coefficient of hydrofoil,and the increase of the number of hydrofoils can improve the power coefficient of the hydrofoils.
