High-Order Unstructured Methods for Large Eddy Simulation and Shape Optimization

Motivated by environmental regulation and international competition, next-generation Canadian aircraft and jet engines must be significantly quieter and more fuel efficient to remain commercially viable. The design of such aircraft will rely heavily on disruptive computational fluid dynamics (CFD) technologies, specifically large eddy simulation (LES), to meet performance and pollution targets. The United States, European Union, and direct competitors to Canadian companies including Rolls Royce, Airbus, and BAE Systems, are currently investing in or adopting LES for aircraft and jet engine design with a projected 2020 timeline. However, this has not been met by similar investment in Canada, yielding a distinct competitive disadvantage. The long-term objective of this research program is to ensure Canadian industry remains competitive by developing novel technologies for LES that are more accurate, reliable, and less expensive. This will be achieved via three specific multi-year research objectives to improve accuracy, reduce cost, and increase the range of applicability of LES: 1) LES in the Vicinity of Complex Geometries, 2) LES using Next-Generation Computer Hardware, and 3) Aerodynamic Shape Optimization using LES. A final product from this research program will be an implementation of these novel technologies in a CFD package made available to Canadian industry partners, enabling the design of commercially viable next-generation aircraft and jet engines in Canada.
