LES of wake flow behind 2.3MW wind turbine

2020-03-26T08:43:08Z (GMT) by Søren Juhl Andersen

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

Liew, J., Urbán, A. M., and Andersen, S. J.: Analytical model for the power-yaw sensitivity of wind turbines operating in full wake, Wind Energ. Sci. Discuss., https://doi.org/10.5194/wes-2019-65

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

n1=10325;

n2=68;

n3=68;

L1 = 9601.319092; % [m]

L2 = 118.310131; % [m]

L3 = 118.425435; % [m]


% Freestream

U0 = 8; % [m/s]

R = 46.5;


% Loading results

count=n1*n2*n3;

fid=fopen('WT006.T1200s.ufluct');

M2=fread(fid,count,'float32');


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;
