[53,72] calculated the resolved turbulent Schmidt number (Sct_Res) at every time step during the simulation and used it in the RANS mass transport equation. The value of the resolved turbulent Schmidt number is theoretically constant at every time step however, because averages are not ...

Equation (1) is called Schmidt decomposition, the coefficients \(\{\lambda _i\}\) are called Schmidt spectrum, and the number \(k=\dim \mathcal {K}_A=\dim \mathcal {K}_B\) is called Schmidt rank. In the usual Hilbert space formulation of quantum mechanics, a pure quantum state ...

However, even for cases with mean current, we believe that using the Schmidt number prescribed by equation (12) provides a better compromise for the concentration time histories at different elevations. Figure 3 Open in figure viewerPowerPoint Comparison of (a) the time-averaged concentration ...

Present values of kL,model are estimated using equation (8). due to the presence of surface contamination in the experiments. It also confirmed that the filtering difference (equation (9)) is negligibly small on present results (e.g. Fig. 4). The surface divergence model is ...
This local (regional) change in turbulent Schmidt number compensates for flaws of Boussinesq approximation in the linear two-equation turbulence modeling of inclined negatively buoyant jets. Comparing to the previous LES results, the RTSN approach combined with the realizable k鈥 \\(\\epsilon \\)...
As long as the velocity field at the water surface meets a two-dimensional continuity equation, the turbulent diffusion coefficient increases at the surface with z3 as at a solid wall. Therefore the Schmidt number exponent is also − 2/3, but the constant in Eq. (13) may be different ...
We performed DNS of passive scalar transport in fully developed turbulent channel flow at a low Reynolds number (Reτ = 180) and moderate Schmidt numbers up to Sc = 49. A high order Finite Volume scheme is used for the passive scalar transport equation. In order to keep the numerical effor...
