Parameterized Wake Model

This folder contains all of the wake data, CFD models, and completed simulations used in the paper: Parameterized Vertical-Axis Wind Turbine Wake Model Using CFD Vorticity Data (included in this folder). Descriptions of each of the items are as follows:<br>CFD VORTICITY/VELOCITY DATAThe .csv files of all of the vorticity and velocity data obtained from the lateral cuts made. Included is a .txt file describing the naming system and a .csv file containing the lengths used for obtaining the lateral cuts (i.e., length reported (m) divided by (30*i) indicates the distances downstream each cut (i) was made at).<br>Files are ordered by:<br>w#_s#_t#.csv<br>w#: indicates windspeed in m/s<br>s#: indicates solidity<br>t#: indicates tip-speed ratio multiplied by 100, for example: 250 = 2.5<br>CFD MODELSThis file contains the SolidWorks part files and the parasolid (*.x_t) files used for the CFD simulations. Base files of the CFD simulations are also included (2D meshed) for each solidity (s1: 0.15, s2: 0.25, s3: 0.5, s4: 0.75, s5:, 1.0). The java macro file can be used in STAR-CCM+ to run the files by specifying each of the parameters desired near the beginning.<br>Also included is the same CFD data used to model the PIV validation study using the specifications in the paper (naca0018piv): <br>Tescione, G., Ragni, D., He, C., Ferreira, C. S., and van Bussel, G., “Near wake flow analysis of a vertical axis wind turbine by stereoscopic particle image velocimetry,” Renewable Energy, Vol. 70, 2014, pp. 47-61.<br>COMPLETED CFD SIMULATIONSThe completed 2D CFD simulations of a 3-bladed VAWT used for the initial parameterized wake model. The simulations were run at wind speeds of 12, 14,15, and 16 m/s, and varying tip-speed ratios and solidities using STAR-CCM+. Each of the files are in a separate zip file with the wind speed and rotation speeds indicated. The naming conventions are similar to the CFD vorticity data with the differences of "ta" standing for time averaged.<br>To reference this data, use the reference of the paper in the folder (http://arc.aiaa.org/doi/10.2514/6.2016-1730).<br>

本文件夹包含论文《基于CFD涡量数据的参数化垂直轴风力机尾流模型》（已存放于本文件夹内）中使用的全部尾流数据、计算流体动力学（Computational Fluid Dynamics，CFD）模型与已完成的仿真算例。各条目说明如下：<br>CFD涡量/速度数据<br>本部分包含所有通过横向切面获取的涡量与速度数据的.csv格式文件。其中附带一份.txt格式文件，用于说明文件命名规则；另有一份.csv格式文件，记录了获取横向切面时所用的长度参数：报告长度（单位：米）除以(30*i)，即可得到每个切面(i)所在的下游距离。<br>文件命名格式为：w#_s#_t#.csv<br>其中w#代表风速（单位：m/s）；s#代表风力机实度；t#代表叶尖速比乘以100，例如：250即对应叶尖速比为2.5。<br>CFD模型<br>本文件夹包含用于CFD仿真的SolidWorks零件文件与parasolid（*.x_t）格式文件。同时附带了对应各实度（s1: 0.15, s2: 0.25, s3: 0.5, s4: 0.75, s5: 1.0）的CFD仿真基础文件（已完成二维网格划分）。可在STAR-CCM+中调用该Java宏文件，通过修改文件开头处的所需参数即可运行仿真。<br>此外还附带了用于复现论文中粒子图像测速（Particle Image Velocimetry，PIV）验证研究的同类型CFD数据（对应配置为naca0018piv），其引用来源如下：<br>Tescione, G., Ragni, D., He, C., Ferreira, C. S., and van Bussel, G., "Near wake flow analysis of a vertical axis wind turbine by stereoscopic particle image velocimetry," Renewable Energy, Vol. 70, 2014, pp. 47-61.<br>已完成的CFD仿真算例<br>本部分包含用于初始参数化尾流模型的三叶垂直轴风力机（Vertical Axis Wind Turbine，VAWT）二维CFD仿真算例。仿真采用STAR-CCM+完成，运行风速分别为12、14、15及16 m/s，同时覆盖了不同叶尖速比与实度参数。每个算例均打包为独立的zip压缩文件，文件名中标注了对应风速与转速。其命名规则与CFD涡量数据类似，仅差异在于以“ta”表示时间平均。<br>如需引用本数据集，请使用本文件夹内论文的引用格式：http://arc.aiaa.org/doi/10.2514/6.2016-1730。
