"WebApr 3, 2024 · It can also be observed from the Table 2 that the sampling frequency for a given simulation increases as the large-eddy turnover time (LETOT) decreases. This was done to ensure that the sampling does not introduce any bias into the temporal statistics. The sampled data were then used to calculate the turbulent correlations. " - Eddy turnover time

WebOct 1, 2013 · The decay period is related to the solar time scale that, for the site considered in this study, was found to last nearly 4 h that, expressed in terms of the nondimensional eddy turnover time, is equivalent to a value close to 30. This contrasts with the previous LES studies where shorter and unrealistic external forcing time scales were used.

WebEddy turnover time This time scale is usually referred to as the eddy turnover time. Equation (3.82) illustrates the importance of the scalar spectral energy transfer rate in determining the scalar dissipation rate in high-Reynolds-number turbulent flows.Indeed, … Richardson's notion of turbulence was that a turbulent flow is composed by "eddies" of different sizes. The sizes define a characteristic length scale for the eddies, which are also characterized by flow velocity scales and time scales (turnover time) dependent on the length scale. The large eddies are unstable and eventually break up originating smaller eddies, and the kinetic energy of the initial large eddy is divided into the smaller eddies that stemmed from it. These smaller eddi…
