The Flux Balance Analysis (FBA) is an approach that combines the description of the flux space F defined by equation (3) with optimization techniques to find a flux distribution v that maximizes the growth rate [ 17, 37, 41].
For the purpose of an equally good description of heat fluxes and material fluxes in open heat transformation processes, a concept for exergetic evaluation of material fluxes is necessary.
A numerical concentration polarization model was developed to enable local description of permeate flux and solute rejection in crossflow reverse osmosis separations.
This flux discontinuity arises inherently from the definition of a mixing cell: the mixing process is included in the balance equation, but does not appear in the description of the flux through the mixing cell.
A comparison of the modeling predictions with the experimental results indicates that a zero-order kinetic model is valid for description of hydrogen flux away from the δ-hydride phase, and that a second-order kinetic model works well for hydrogen desorption from α-Zr if the activation energy of desorption is optimized to be 70% of the value reported in the literature.
It has previously been observed experimentally that gene-expression profiles provide qualitative descriptions of metabolic flux activity [ 53, 54].
Heuristic interpolations between the fluid and the porous medium parameters have been commonly used; however, there is no guarantee that such models can provide an accurate description of the mass flux.
Mielich and Bremer ([2013]) shows that for F2 region trends F10.7 is even better than E10.7 index (Tobiska's ionospheric data-based index for description of solar EUV flux, which is close to F10.7) due to problems of the latter in 1957 to 1958.
A transport equation for the density of the liquid interface represents the jet break-up, subsequent atomization, and space time evolution of the liquid surface area which combined with a local description of the vaporization flux provides the volumetric source of gaseous oxygen.
The proper description of ion diffusion fluxes is important in the design and development of separation processes such as ion exchange, electrodialysis, metals extraction and fuel cells.
