Eddy turnover time
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. Webrespective flows, it may be recast as the relative large-eddy turnover time scale between the FST and boundary layer, evolving as the boundary layer grows and the unforced free …
