The setup of turbulent mixing models is done in the mixingProperties dictionary of the corresponding case.
Activating the mixing model
The mixing model is activated using the mixingModel keyword and setting it to the desired model type:
Sub-models are specified in the corresponding Coeff dictionary.
Selecting the diffusion model
The diffusion model is selected in the diffusionModel sub-dictionary:
gammaLam gammaLam [ 0 2 -1 0 0 0 0 ] 1.0e-6;
Selecting the mixing kernel
The mixing kernel is activated using the mixing keyword and specifying the mixing kernel and the corresponding parameters in the mixingKernel sub-dictionary:
Cphi Cphi [ 0 0 0 0 0 0 0 ] 2.0;
c c [ 0 0 0 0 0 0 0 ] 1.0;
Integration of the sub-models
Sub-models are integrated using the realizable ODE solver implemented in general form into OpenQBMM. Settings for this solver are specified in the mixingProperties dictionary, as explained here.
