Abstract
ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force CFD simulation codes. The significance of the innovation is that it will improve the predictive capabilities of these codes with regard to the interaction of highly-unsteady, turbulent flows with combustion processes. As a result, CFD simulations will be able to capture more accurately and in a cost effective manner the complex flow physics governing propulsion system performance and stability. This combustion model library will involve a multi-layered approach that includes a range of formulations applicable to different flame regimes and with varying degrees of computational costs. By providing a viable and accurate modeling strategy of lasting relevance applicable for routine analysis, the appropriate model may be chosen for a particular problem/scenario while minimizing computational cost. BENEFIT: In order to ensure portability and easy coupling with appropriate reacting CFD flow solvers, the proposed modeling strategy will be implemented within a portable library featuring a standardized multi-language Application Programming Interface (API). This API library represents a viable commercial product to be licensed to customers who require access to advanced turbulent combustion models in their CFD flow solver of choice. Combustion models available in the API library will be applicable to a wide range of military and commercial combustion applications, including gas turbines, augmentors, power generation systems, furnaces, incinerators, internal combustion engines, etc. The commercial opportunities for this standardized API library are enormous. CRAFT Tech will market this library for license to commercial customers as well as to other CFD flow solver development companies.
