In this paper, a novel class of fixed-order, energy-based hybrid decentralized controllers is proposed as a means for achieving enhanced energy dissipation in large-scale lossless and dissipative dynamical systems.
When electrical power input is assumed to be a measure for turbulent production, dimensional arguments based on a volume-averaged large-scale estimate for viscous dissipation lead to the foregoing correlation for homogeneous turbulence.
The turbulence energy interaction between gas and solids was described by different k12 transport equations, while the particle dissipation by the large-scale gas turbulent motion was taken into account through a drift velocity.
The growth of the large scales, and dissipation of kinetic energy is captured well at resolutions greater than 323, or when using numerical methods of higher than third-order accuracy.
This depletion is caused by the large-scale thermospheric wind disturbances due to Joule heating dissipation in the auroral zone.
Earlier the efficiency of large-scale disturbances in the thermosphere, owing to the dissipation of small-scale IGWs, was studied using as example the model of the disturbances generated by the solar terminator (Karpov and Bessarab, 2008).
Results from model calculations with various wave periods and an explanation of the excitation mechanisms of large-scale disturbances owing to the small-scale IGWs dissipation are given by Karpov and Bessarab (2008).
Subgrid-scale dissipation of momentum in numerical models of the large-scale ocean circulation is commonly parameterized as a viscous diffusion resulting from the divergence of a stress tensor of the form σ = A ∇u.
Since 1997, the ECOHAB Program has sponsored nearly 100 projects with topics ranging from molecular aspects of HAB detection to large-scale, multidisciplinary regional studies of bloom formation, maintenance, and dissipation.
The flow motion is turbulent, and it occurs over a wide range of length and time scales, from equipment-dependent large-scale coherent structures to the smallest-scale eddies where energy dissipation takes place.
This is done by adding to the large-scale motion an eddy viscosity that characterizes the transport and dissipation of energy in the smaller-scale flow or any such feature that occurs at too small a scale to be captured by the grid.
