### 7.12.3. Peters Correlation

The Peters correlation for turbulent burning velocity was originally developed for the G-equation combustion model (N. Peters [37]). For CFX, it was adopted to be used with the burning velocity model.

where , , , and .

Turbulence effects are modeled as a function of the ratio between the integral turbulence length scale, , and the laminar flame thickness, .

The diffusion coefficient for the flame is computed from molecular properties of the unburnt mixture indicated by the subscript u. The default values for the model constants are listed in Table 7.5: Default Model Coefficients for Peters Turbulent Burning Velocity Correlation.
