The main goal of this project is to perform efficient and accurate simulations of the turbulent compressible flow and generated noise on the new high-speed gas turbines at operation conditions, with the aim of supporting engineers in the design of efficient engines and effective noise reduction solutions. The main difficulty is to correctly simulate, in an acceptable wall-clock time, high Reynolds and high Mach numbers turbulent flows with important regions of separation and the different length scales and amplitudes among the acoustic and the flow fields.

In this project we propose to tackle these problems by introducing high-order Galerkin methods and a skin friction boundary condition technique extended to compressible flows. Both techniques demonstrated impressive performance results on a different context. Given the fellows expertise in compressible flows, and her Third Country hosts expertise in high-order Galerkin methods, we are in a unique position to advance in the solution of this problem. A high performance computing simulation tool developed at the host institution will be used and developed as open source within this project. To go one step further within this interdisciplinary subject, we will establish a close collaboration with a company in the host country specialized in testing aerospace materials, where the fellow will spend one month of research. During this visit, the simulation results of their turbine prototypes will be analyzed and will be validated against their experimental data.
