| Summary | 0003982: egrMixture does not correctly consider egr fraction for low fuel mass fractions | ||||
| Description | egrMixture assumes that parts of the "unburnt" (i.e. b=1) contain already burnt products. Thus, in https://github.com/OpenFOAM/OpenFOAM-dev/blob/master/src/thermophysicalModels/multicomponentThermo/mixtures/egrMixture/egrMixture.C#L77, just returning the oxidant if the fuel mass fraction is very low is not correct. Instead, the correct fractions of oxidant and products should be returned - return oxidant_; + mixture_ = (1.0 - egr)*oxidant_; + mixture_ += egr*products_; I attached a diff which would make egrMixture more corret. | ||||
