<div>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:</div><div><br></div><div>CFD VELOCITY/VORTICITY DATA</div>The .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).<div><br></div><div><div>Files are ordered by:</div><div><br></div><div>w#_s#_t#.csv</div><div><br></div><div>w#: indicates windspeed in m/s</div><div><br></div><div>s#: indicates solidity</div><div><br></div><div>t#: indicates tip-speed ratio multiplied by 100, for example: 250 = 2.5</div></div><div><br></div><div>The files that begin with "ConstDia_" follow the same naming convention for solidity and tip-speed ratio, but are all run at a wind speed of 15 m/s and the data is divided into 30 segments at consecutive diameter distances (1D, 2D, 3D, ... 30D).</div><div><br></div><div>CFD MODELS</div><div>This 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 along with 2D meshed versions ready to run for each solidity (s1: 0.15, s2: 0.25, s3: 0.5, s4: 0.75, s5:, 1.0).  The java macro files can be used in STAR-CCM+ to mesh and run the files by specifying each of the parameters desired near the beginning ( and<div><br></div><div>Also included is the same CFD data used to model the PIV validation study using the specifications in the paper from: </div><div><br></div><div>Tescione, G., Ragni, D., He, C., Ferreira, C.
