16.1.2 Defining the Problem Type

Your first task is to define the type of reaction system and reaction model that you intend to use. This includes selection of the following options:

• Non-premixed or partially premixed model option (see Chapter  18).

• Equilibrium chemistry model, steady laminar flamelet model, unsteady laminar flamelet model, or diesel unsteady flamelet.

• Adiabatic or non-adiabatic modeling options (see this section in the separate Theory Guide).

• Addition of a secondary stream (equilibrium model only).

• Empirically defined fuel and/or secondary stream composition (equilibrium model only).

You can make these model selections using the Species Model dialog box (Figure  16.2.1).
