摘要

水平轴流式风力涡轮机（HAWT）的性能受到风尖速比（TSR）和网格分布差异的影响。因此，研究不同网格分辨率对风机性能的影响非常重要。为此，我们使用了一个 0.65 米的最佳扭曲锥形（OPT）叶片，并采用了不同的入口速度和 TSR。本研究在商用 ANSYS Fluent CFD 软件中使用了基于雷诺平均纳维斯托克斯（RANS）方法的 k-ꞷ 剪切应力传输（SST）。该模拟采用移动比率框架 (MRF) 方法进行。为找到最佳网格分辨率，进行了网格独立性测试 (GIT) 以比较功率系数 (Cp)。结果显示，当入口速度为 8 米/秒时的 Cp 为 0.2608 时，TSR 6 的 HAWT 性能最佳。

Impact Tip Speed Ratio in Performance Analysis for Horizontal Axis Wind Turbine (HAWT) with Optimal Twist and Tapered (OPT) Blade Shape

Performance for Horizontal Axial Wind Turbine (HAWT) is influenced by the difference in tip speed ratio (TSR) and mesh distribution. The objective of this article is to study the optimal performance of wind turbines when subjected to different mesh resolution, TSR and wind speed velocity.Therefore, it is important to study the effects of different mesh resolutions in terms of wind turbine performance. To achieve that, a 0.65m optimal twist and tapered (OPT) blade is used with various inlet velocities and TSR. This study uses the k-ꞷ shear-stress transport (SST) based Reynold-Average Navier Stokes (RANS) approach in commercial ANSYS Fluent CFD software. This simulation was performed using the Moving Ratio Frame (MRF) method. To find the optimum grid resolution, a Grid Independence Test (GIT) was conducted comparing the coefficient of power (Cp). From the RESULT, TSR 6 shows the best HAWT performance when Cp for inlet velocity 8 m/s is 0.2608.
