Re: intermittent FF wind field with TurbSim

Hi Bonnie, Thanks for your quick response. Pardon me if I am stretching this a bit more. The obtained 180 degrees horizontal angle is not user-defined. TurbSim itself calculates the horizontal angle to be 180 or -180 regardless, and flips the sign of u and v components. For a TIMESR input (rotated t...

Re: intermittent FF wind field with TurbSim

Hi Bonnie, Thanks for the reply. I realized where the problem was. The original wind time series I fed into TurbSim was at different height than the hub height and I let TurbSim do the extrapolation using appropriate PLEXP value. With revision, I extrapolated the wind data to the hub height outside ...

intermittent FF wind field with TurbSim

Hi Bonnie, I have a FAST model of 5 kW HAWT; aiming to instigate the effect of turbulence and intermittency in the wind flow field on the fatigue and loading of the turbine blades. I am feeding a single-point measured wind time history data into TurbSim (using TIMESR) and generated a full-field file...
