Jun 07, 2012  An arbitrary level of TKE was introduced in the numerical simulations (both present, as well as Teixeira and Belcher) as an initial condition. In the experiments, however, the TKE was allowed to occur naturally. Therefore, the absolute values of turbulence intensity in the laboratory and in the numerical simulations are not expected to match.
