Turbulent Reactive Flow in Stirred Tank

Modeling of the molecular diffusion-chemical reaction processes to predict the local reaction rate. [Pg.707]

Modeling of the turbulent field in enough detail to approximate the rate controlling steps of turbulent mixing. [Pg.708]

Modeling of local turbulent mixing of the heat and species concentrations. [Pg.708]

The relative importance of the specific physical phenomena mentioned strongly depends on the type of flow under consideration. In this section, the discussion is limited to single-phase, constant density flows under isothermal conditions with constant viscosity and equal diffusivities. The emphasis is placed on the modeling of turbulent mixing and on the interactions between turbulent mixing and chemical reactions in non-premixed turbulent reacting flows. [Pg.708]

The velocity field in these flows is governed by the incompressible Navier-Stokes equation (1.385) and the corresponding continuity relation (1.382). For incompressible fluids a generic transport equation for scalar species mass concentration fields can be deduced from (1.454) and expressed as  [Pg.708]


By far the most widely employed models for turbulent reactive flows in stirred tanks are based on the Reynolds averaged Navier Stokes (RANS) equation. This is a moment equation containing quantities that are averaged over the whole wave spectra, as explained in sect 1.2.7. [Pg.710]
