Wind Generator

Inflow data play an important role in the numerical simulation of wind loads using large eddy simulation. The inlet generator generates transient inlet data for the efficient modeling of a neutrally stable atmospheric boundary layer. Input parameters determine the statistical description of the numerical wind field such as mean velocity profile, turbulence intensity profile, energy spectrum and length scale. A three-dimensional frozen wind field is generated and saved in an HDF5-formatted file for later use in a numerical wind load simulation. The transformation from the frozen wind field into a transient inflow is realized using Taylor's frozen turbulence hypothesis. The inlet data is interpolated onto the grid points of the LES domain inlet.
