摘要
为了研究涡轮三维叶型的水力性能,基于等环量法提出了一种涡轮三维叶型的理论造型方法,并推导出了该涡轮三维叶型的特性参数计算方法.利用ANSYS Fluent对同尺寸下的涡轮三维叶型和二维叶型进行了数值模拟分析其水力特性.研究结果表明:与二维叶型相比,涡轮三维叶型的压降减小约50%,水力效率提高约 5%.对比了三维叶型涡轮扭矩的理论计算结果与仿真结果,发现它们的误差在10%左右,在实际工程允许范围内.研究结果可为涡轮三维叶型的设计提供理论依据.
Abstract
In order to study the hydraulic performance of turbine 3D blade profile,a theoretical molding method for turbine 3D blade profile was proposed based on the equal circulation method,and a calculation method for the characteristic parameters of the turbine 3D blade profile was derived.Then,the ANSYS Fluent software was used to conduct numerical simulation on the turbine 3D blade profile and 2D blade profile of the same size,and analyze the hydraulic characteristics of them.The research results show that compared with 2D blade profile,the pressure drop of turbine 3D blade profile is reduced by about 50%,and the hydraulic efficiency is improved by a-bout 5%;the error between theoretical calculation and simulation results of 3D blade profile turbine torque is about 10%,within the allowable range of actual engineering.The research results provide a theoretical basis for the de-sign of turbine 3D blade profile.
