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 (w##cfd.zip) 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>
