The Technical Objectives presented in this Phase I proposal directly address a topic in the NASA SBIR solicitation for low emissions/clean power aircraft combustors. The "compact" low-dimensional chemical kinetic mechanisms proposed for modeling of real aviation fuel combustion chemistry will support physics-based CFD development of next-generation engines such as those employing lean direct injection (LDI) technology. Reacting flow simulation platforms like NASA's National Combustion Code (NCC), as well as ANSYS, KIVA, and OpenFOAM, require mechanisms sufficiently compact so as to be tractable for multi-dimensional, multi-physics, CFD simulations, but which also preserve the predictive fidelity of more detailed kinetic mechanisms. Importantly, the present framework permits the consideration of a variety of real fuels, including alternative fuels derived from a variety of non-petroleum resources. Evaluation of such alternative fuels is among the major NASA research thrusts under the general topic of propulsion.
The commercial product foreseen from this SBIR program is a stand-alone, novice-friendly real fuel kinetic mechanism generator software package that can interface with commercially-available computational fluid dynamics (CFD) codes. Accordingly, potential customers may include the companies supplying ANSYS, CFD-ACE+, or COMSOL, as well as industrial users with proprietary in-house codes. Application of compact real fuel kinetic models has broad appeal to automotive, aerospace, and marine propulsion industries, both for civilian and DoD applications.
