LES of wake flow behind 2.3MW wind turbine
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
This database contains inflow and wake flow behind a 2.3MW turbine simulated using large eddy simulation(LES) in EllipSys3D. All three velocity components are given for downstream distances from 1R to 23R, where R = 46.5m. Please see

for additional details.
The velocity components are stored with the same format as Mann boxes.
The data can be read using the following in Matlab:
% Dimensions of turbulence box
L1 = 9601.319092; % [m]
L2 = 118.310131; % [m]
L3 = 118.425435; % [m]
U0 = 8; % [m/s]
R = 46.5;
% Loading results
U = U0*reshape(M2,n3,n2,n1);
% X and Y vectors
x = linspace(0,L2,n2)-L2/2;
y = linspace(0,L3,n3)-L3/2;
