Computational Fluid Dynamics (CFD) has become an indispensable tool in designing turbomachinery components in all sectors of Rolls-Royce business units namely, Aerospace, Industrial, Marine and Nuclear. Increasingly sophisticated search and optimisation techniques are used based on both traditional optimisation methods as well as, design of computer experiment techniques, advanced surrogate methods, and evolutionary optimisation techniques. Geometry and data representation as well as access, queuing and loading control of large high performance computing clusters are areas of research to establish the most efficient techniques for improving the performance of an already highly efficient modern jet engine.

This presentation focuses on a high fidelity design optimisation framework called SOPHY that is used in Rolls-Royce to provide parametric geometry, automatic meshing, advanced design-space search algorithms, accurate and robust CFD methodology and post-processing. The significance of including the so-called real geometry features and interaction of turbomachinery components in the optimisation cycle are discussed. Examples are drawn from real world applications of the SOPHY design systems in an engine project.
