Mixing two streams. #. Since reactors can have multiple inlets and outlets, they can be used to implement mixers, splitters, etc. In this example, air and methane are mixed in stoichiometric proportions. Due to the low temperature, no reactions occur. Note that the air stream and the methane stream use different reaction mechanisms, with

Reactors and Reactor Networks. #. In Cantera, a reactor network represents a set of one or more homogeneous reactors and reacting surfaces that may be connected to each other and to the environment through devices representing mass flow, heat transfer, and moving walls. The system is generally unsteady – that is, all states are functions of time.
