Abstract:
Scramjet propulsion has the potential to power high Mach number flight without the need to carry its own oxidizer like a rocket, thus significantly reducing the flight weight of the vehicle. Numerical simulations will play an increasingly important role in the development of scramjet engines. Hydrocarbon fuels are advantageous for scramjet propulsion because of their higher energy density and ease of transport. CPU and memory limitations prohibit implementation of full detailed chemistry of hydrocarbon fuels into 3-D CFD simulations, even using the latest massively parallel computers. The proposed project will develop a hydrocarbon chemical kinetics modeling capability suitable for scramjet design applications by 1. Improving existing chemical kinetic mechanisms for JP-7 and JP-8 focusing on the low pressures and high temperatures found in a scramjet combustor using density functional and ab initio calculations of thermochemical properties and chemical kinetic rates, 2. Automatically optimizing reduced mechanisms using a genetic algorithm, and 3. Implementing advanced chemical source term tabulation techniques (ISAT) that include branch trimming and multi-tree capabilities that give much better speed-up than earlier versions. In Phase II the kinetics will be further refined by comparison to experiments tailored to scramjet conditions and improvements for parallel ISAT will be implemented.Small Business Information at Submission:Research Institution Information:Reaction Engineering International
