Cascade energy

The turbulent energy, extracted from the mean flow, passes through the energy cascade and is ultimately converted into internal energy by viscous dissipation. [Pg.67]

Figure 4.9. Sketch of CSTR representation of the SR model for 1 < Sc. Each wavenumber band is assumed to be well mixed in the sense that it can be represented by a single variable <p 2)n- Scalar energy cascades from large scales to the dissipative range where it is destroyed. Backscatter also occurs in the opposite direction, and ensures that any arbitrary initial spectrum will eventually attain a self-similar equilibrium form. In the presence of a mean scalar gradient, scalar energy is added to the system by the scalar-flux energy spectrum. The fraction of this energy that falls in a particular wavenumber band is determined by forcing the self-similar spectrum for Sc = 1 to be the same for all values of the mean-gradient source term.

When there are more conversions available that are mutually compatible, process technological solutions (e.g., membranes) can further fully exploit low-energy cascade-type reaction sequences (instead of the other way around - non-compatible conversion steps will always demand high separation costs). [Pg.410]

Specifically, in the first step of the energy cascade, the light is captured by the DVB dimer located in the core of the complex. The energy is then transferred to peripherally located bilins (MBV, PCB 158) through a complex network of interactions that, owing to the very similar timescales and spectral features, are hard to separate. Probably, energy migration from DBV bilins to the MBV bilins occurs on a timescale (T) 0.6 ps) faster than the transfer... [Pg.17]
