Species Source Term Mapping for Reacting Flow CFD

Simulations of reacting flow in applications such as scramjet engines are currently limited in their utility or accuracy by the chemistry sub-models employed. Accurate chemistry models for hydrocarbon fuels are particularly problematic since the detailed kinetic mechanisms can be highly complex, essentially prohibiting obtaining a timely solution. Simpler global chemistry models, while tractable, are notoriously inaccurate except over narrow ranges of conditions. Reactions Systems therefore proposes to explore a new approach to capturing the detailed chemistry in a reduced multi-dimensional format that could combine the advantages of ISAT with recent RSLLC proprietary innovations in species reduction.
