At point I the chemical production rate can no longer be balanced by diffusive losses, and the flamelet ignites, jumping up on the upper portion of the curve.
Equation (16), which is how the local value of the scalar dissipation rate is calculated in CFD based flamelet combustion models, shows that the scalar dissipation rate is determined by the turbulence levels and the mixture gradients.
In order to derive an equation for a characteristic scalar dissipation rate, a dimensional analysis was done to create dimensional homogeneity with the scalar dissipation rate used in CFD flamelet models.
The critical scalar dissipation rate for ignition can be determined by using a one-dimensional flamelet combustion model, which was briefly introduced earlier.
The local flame structure is defined by the flamelet equations that are solved for the progress variable C and enthalpy assuming unity Lewis number [7] in the mixture fraction space:
z] which is function of the scalar dissipation rate at stoichiometric mixture fraction conditions [mathematical expression not reproducible] which is computed for each flamelet.
The chemical composition in the CFD domain is computed from the mixture fraction, its variance and the flamelet marker distribution.
The details of the proposed turbulent combustion model, which will be referred to as the tabulated flamelet model (TFM), will be briefly discussed in this section.
When the transport equations for the species mass fractions and energy are transformed into the mixture fraction space (based on the flamelet assumption [12]), the resulting equations are termed as the flamelet equations which are shown below.
The scalar dissipation rate for each flamelet is determined as:
