This submission allow the user for generation of three-dimensional turbulent wind fields, by employing a Kaimal spectrum and IEC-based coherence function. Furthermore, it is possible to export the generated wind fields as FAST-compatible .bts, in order to simulate wind turbine dynamic behavior in presence of stochastic wind. Required inputs are: - Average wind speed at hub height, U0 [m/s] - Desired turbulence intensity, I0 [ ] - Hub height, HubHt [m] - Random seed - Number of grid points on z-axis, Nz (odd number) - Number of grid points on y-axis, Ny (odd number) - Grid width, Ly [m] - Grid height, Lz [m] - Time step, dt [s] - Simulation length, T [s] (generally 600s) - Length scales, (xLu,xLv,xLw) [m] - Vertical wind shear exponent - Coherence decay, a - Coherence length scale, Lc [m]. The file GenerateOneBTS.m better highlights how the different functions operate.
