Applying computational science and engineering to the design and analysis of high-performance compressors makes it possible to understand unsteady flow effects in gas turbine engines. Simulations have produced numerical data of greatly improved geometric, physical, and numerical fidelity than previously possible, helping next-generation engines achieve unprecedented performance.
