Let me make a simple example. For H2/Air combustion system, I will not need to solve all species. Some species, say OH, are linear combined with other species, e.g. OH=0.5k1H + 1.0k2O Where k1 and k2 are in Arrhenius expression. In this case, I should first calculate OH using mentioned expression, then as input for the calculation of other species. However, I do not know how to do that. Does anyone have suggestions/examples? Best regards
