Abstract

The ideal stirred reactor, where mixing and molecular diffusion are fast compared to the chemical reactions being studied and where backmixing is sufficient to eliminate all composition gradients within the reactor, is a modeling tool of classic and continuing interest in "reaction engineerig". Some reactions, however, can be faster than the mixing process and interpretation of data taken under these conditions may require modeling of turbulent mixing and its interaction with the chemical processes of interest. In this article, some progress on application of the Curl coalescence-redispersion model, to description of the mixing chemistry interaction is reported. Comparison with experimental results from fuel-lean CO H2 combustion indicates that for fast reactions, such as CO H2air, it is important to take the jet mixing nature of the flow into account. For the slower rich C2H2air reaction the exit gas composition can be quite well modeled by assuming a simple stirred reactor. Progress on cold flow tracer studies and two dimensional modeling of the jet mixing is also reported.
