摘要 基于叶素-动量(BEM)理论,建立了水平轴海流机(HMCT)水动力学设计及校核模型;对海流机空化问题进行了分析,提出了海流机设计中预防空化的措施;校核模型考虑了叶尖损失修正、有限叶片数影响等因素,采用失速模型得到失速状态下的翼型升阻特性。编制了水平轴海流机设计及校核程序,通过与试验模型对比,验证了校核模型的可行性。设计了直径为20m的水平轴海流机样机HMCT20并对其进行了校核,其功率系数达到设计要求。 A hydraulic design and performance validation model for horizontal marine current turbine(HMCT) is developed by applying the blade element momentum(BEM) theory.Cavitation effect is considered in the design model,and correction of tip loss,finite blade effect and hydrofoil characteristic under stalled conditions are considered in the validation model.A FORTRAN code is used to implement the model for designing a blade of 20m in diameter.The code is validated through comparison with experimental data.
