Navy funds IAI to develop a high-fidelity, multi-physics based analysis and design optimization tool for advanced exhaust systems.

The energy challenges faced by the U.S. Navy are daunting, given the increasing global demand for energy, the dwindling energy reserves, and demand for enhanced environmental stewardship. The Navy’s environmental footprint consists of both emissions and noise generated daily around the world. Engine noise has an adverse effect upon personnel and communities around naval air bases and training sites. Although noise abatement technologies have received considerable attention in the commercial sector, military combat aircraft designs require high-thrust engines and afterburners, resulting in noise generation. IAI and its collaborators at The Stanford University will develop the “Coupled Multi-physics Analysis and Design Optimization of nozzles (COMANDO)” tool, to streamline exhaust nozzle design, improve efficiency, and reduce noise generation. Jet and nozzle flow possess a complex combination of turbulent mixing, temperature fluctuation, and compressibility effects, which may be further complicated by chemical reactions and shear layer instabilities. To accurately capture the acoustic signature of novel engine nozzle configurations and designs, high-fidelity physics-based analysis becomes a necessity. COMANDO will be able to accurately capture the acoustic signatures of engine nozzle configurations, using high-fidelity, multi-physics based analyses and design optimization. COMANDO combines state of the art nozzle flow modeling techniques and Multi-Disciplinary Optimization (MDO) in a high performance computing environment to enable scientists to optimize nozzle design, engine-airframe integration, and other related design challenges.
