3. Numerical method for calculating a spectrum

3.1 Issues

Turbulent excitation spectra can be calculated using a variety of methods, both analytical and numerical. The cost of calculation increases with the expected accuracy, and for industrial applications, a compromise has to be made between the two requirements (figure 12 ).

Empirical models, detailed in § 2
