How is turbulence measured
Web14 feb. 2024 · The turbulence spectrum expresses how the turbulence energy is distributed among various frequencies. Typically, this would be represented by a model spectrum, which is a function of the current magnitude U, variance and length scales, L. The Kaimal and von Kármán spectra are the most commonly used models in commercial … WebMeasurements of turbulence are essential to understand and quantify the transport and dispersal of heat, moisture, momentum, and trace gases within the planetary boundary …
