Description
- Simple infinitely fast chemistry combustion model based on the principle
- mixed is burnt. Additional parameter C is used to distribute the heat
- release rate.in time
+ Partially stirred reactor combustion model. The model calculates a finite
+ rate, based on both turbulence and chemistry time scales. Depending on
+ mesh resolution, the Cmix parameter can be used to scale the turbulence
+ mixing time scale.
