| Abstract: | The methods for modelling nature wind flow in boundary layer wind tunnel were discussed in this paper. The profile of time mean velocity and turbulence intensity, power spectrum density, and turbulence scale length should be simulated before the model testing. More attention should be paid in the data collecting and processing when the calibration of atmosphere boundary layer flow field was conducted . |
