Detailed Description

Solver module for compressible premixed/partially-premixed combustion with turbulence modelling.

Combusting RANS code using the Weller b-Xi two-equation combustion model. Xi may be obtained by either the solution of the Xi transport equation or from an algebraic expression.

Reference:

    Weller, H. G. (1993).
    The development of a new flame area combustion model
    using conditional averaging.
    Thermo-fluids section report TF 9307.

Both approaches are based on Gulder's flame speed correlation which has been shown to be appropriate by comparison with the results from the spectral model.

Reference:

    Weller, H. G., Marooney, C. J., & Gosman, A. D. (1991, January).
    A new spectral method for calculation of the time-varying area
    of a laminar flame in homogeneous turbulence.
    In Symposium (International) on Combustion
    (Vol. 23, No. 1, pp. 629-636). Elsevier.

Strain effects are incorporated directly into the Xi equation but not in the algebraic approximation. Further work need to be done on this issue, particularly regarding the enhanced removal rate caused by flame compression. Analysis using results of the spectral model will be required.

For cases involving very lean Propane flames or other flames which are very strain-sensitive, a transport equation for the laminar flame speed is present. This equation is derived using heuristic arguments involving the strain time scale and the strain-rate at extinction. the transport velocity is the same as that for the Xi equation.

Reference:

    Weller, H. G., Tabor, G., Gosman, A. D., & Fureby, C. (1998, January).
    Application of a flame-wrinkling LES combustion model
    to a turbulent mixing layer.
    In Symposium (International) on combustion
    (Vol. 27, No. 1, pp. 899-907). Elsevier.

For inhomogeneous mixtures, in addition to the regress variable b, it is necessary to solve for the mixture-fraction ft provided by the leanInhomogeneousMixture and also the fuel mass-fraction fu if there are rich regions in the mixture, provided by the inhomogeneousMixture. Details of the extension of the Weller b-Xi combustion model to non-premixed combustion can be found in the Technical Report TR/HGW/03.

Reference:

    Weller, H. G. (2002, August).
    The Application of the Weller Combustion Models to
    Non-Premixed Combustion.
    (Technical Report TR/HGW/03)

For inhomogeneous mixtures with exhaust gas re-circulation it is necessary to additionally solve for the recirculated exhaust gas mass-fraction egr which is provided by the inhomogeneousEGRMixture mixture.

Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and pseudo-transient and steady simulations.

Optional fvModels and fvConstraints are provided to enhance the simulation in many ways including adding various sources, chemical reactions, combustion, Lagrangian particles, radiation, surface film etc. and constraining or limiting the solution.
