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 DATAThe .csv files of all of the vorticity 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, rotation rates of 17 and 18 rad/sec, 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 and _r##_ indicating a specified rotation rate rather than a wind speed.<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）所使用的全部尾流数据、CFD模型与已完成的仿真计算。各文件说明如下：

### CFD涡量数据集
包含所有通过横向截面截取得到的涡量数据的.csv格式文件。另有一份.txt文件说明命名规则，以及一份.csv文件记录了用于生成横向截面的截取长度参数：以米为单位的报告长度除以(30*i)，即可得到第i个截面所在的下游轴向距离。

文件命名格式为：w#_s#_t#.csv
其中：
w# 代表风速，单位为m/s；
s# 代表风力机实度；
t# 代表叶尖速比乘以100，例如取值250即对应叶尖速比2.5。

### CFD模型文件
包含用于CFD仿真的SolidWorks零件文件与 parasolid（*.x_t）格式文件。同时提供了对应五种实度（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+软件中调用该Java宏文件，只需在文件起始位置指定所需的各项仿真参数即可运行。

此外还包含了用于复现论文中立体粒子图像测速法（Stereoscopic Particle Image Velocimetry，PIV）验证研究的同规格CFD数据（对应标识naca0018piv），相关参考文献如下：

### 已完成CFD仿真结果
包含用于构建初始参数化尾流模型的三叶垂直轴风力机二维CFD仿真数据。本次仿真采用STAR-CCM+完成，覆盖的工况参数包括：风速12、14、15、16 m/s，旋转速率17、18 rad/s，以及多种叶尖速比与实度组合。每个工况的仿真结果均打包为独立的ZIP压缩文件，文件名中标注了对应风速与旋转速率。

该数据集的命名规则与CFD涡量数据集类似，区别在于：“ta”代表时间平均结果，“_r##_”用于标识指定的旋转速率，而非风速参数。
