Parameterized Wake Model

Listed in DataCite

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).

Description

Descriptions of each of the items are as follows: 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).

Files are ordered by: w#_s#_t#.csv w#: indicates windspeed in m/s s#: indicates solidity t#: indicates tip-speed ratio multiplied by 100, for example: 250 = 2.5 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.

Also included is the same CFD data used to model the PIV validation study using the specifications in the paper (naca0018piv): 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. 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+. 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.
