The developed software will formalize and streamline the process of high-order curved volume mesh generation, and flow calculation within a single all-encompassing framework, removing the bottleneck between geometric definition and flow solution. The software will enable wide use of CFD solvers with high-order schemes. These schemes are especially efficient for the prediction of noise mechanisms and propagation for engine, fan, duct, propellers, and airframes, and for the analysis of wake/frame interaction induced noise and vibrations. The developed technology will fulfill several goals of NASA Technology Roadmap TA15 by a) enabling design of airframe configurations with high levels of aerodynamic performance and reduced noise, b) reduction of turbofan propulsion noise and emissions, and c) reduction of perceived noise and aircraft fuel burn through integrated airframe-engine concepts.
The proposed technology provides a viable tool for several commercial applications such as wing-trailing vortex dynamics of large civil aircraft, analysis of noise generated by the landing gear of civil aircraft, and others. The enabling technology of high-order low-dissipation CFD solver is also applicable to a broad range of applications that involve embedded flow features requiring high resolution with limited grid size. Such applications include turbomachinery, cavitation, biomedical, electronic cooling, and many others.
