• One-dimensional, uniform discretisation of fluid space in terms of:-
  • concentration,
  • temperature,
  • scalar variable, i.e. mixture fraction, and
  • velocity component.

• Appropriate model (K-e, LVEL, Prandtl etc.) to be used for hydrodynamics turbulence from that turbulence viscosity and micromixing time scales are deduced.

• Coupling-splitting hypotheses:
  • Promiscuos Mendelian by DBS
  • Selective Mean by SVZ

• Reynolds concept for the near-wall cells, according to which:
  • fluid is conveyed to the wall at a finite rate per unit area, and is there brought to equilibrium in respect of velocity and temperature and
  the assumption that the rate of transfer is calculable from a conventional logarithmic-law "wall-function",

• Micromixing rates away from the wall:
  constant*mixture density*mother-fluid-mass fraction *
  father-fluid-mass fraction /time scale
