CFD Validation Database for NACA HFSX Hydrodynamics

The NACA HFSX hydrofoil is used in numerous renewable energy applications including marine current turbines (MCTs) which operate at relatively low Reynolds number (in this database Re=190,000). The flow around NACA HFSX hydrofoil at such Re value is transitional which makes the establishment of proper CFD models quite challenging. In the present work, we propose an open-source CFD validation and benchmarking database for this important hydrofoil using the Shear-Stress Transport version of Wilcox’s k-ω turbulence model (SSTk-ω). This validation database aims at providing means of CFD validation to the community for such important application. The files in this database are provided to the CFD community, which includes the setup and solution files of ANSYS Fluent® simulations at angle-of-attack ranging from 0 to 16 degrees. The database is established based on comparison with experimental measurement from (Goundar & Ahmed, 2013, Applied Energy) for the coefficients of lift (C_l) and pressure (C_po) with average error that is considerably lower than any published study at such Reynolds number.NACA HFSX水翼（NACA HFSX hydrofoil）被广泛应用于各类可再生能源领域，其中包括工作于较低雷诺数环境的潮流涡轮机（marine current turbines，MCTs），本数据集所采用的雷诺数为190000。在此雷诺数下，NACA HFSX水翼周围的流场处于转捩状态，这为合适的计算流体动力学（Computational Fluid Dynamics，CFD）模型的构建带来了极大挑战。本研究针对这款重要水翼，基于威尔科克斯（Wilcox）k-ω湍流模型的剪切应力输运版本（SST k-ω），构建了一款开源的CFD验证与基准数据集。该验证数据集旨在为计算流体动力学领域的研究者提供此类重要应用场景的验证手段。本数据集面向CFD领域开放全部文件，其中包含攻角范围为0至16度的ANSYS Fluent®仿真的设置文件与求解结果文件。本数据集的构建以升力系数（C_l）与压力系数（C_po）的实验测量数据为基准，实验数据源自《Applied Energy》2013年发表的Goundar与Ahmed的研究，且本数据集的平均误差显著低于当前已发表的同雷诺数下的相关研究成果。
