Context / Contexte

One path for sustainable development is the development of more efficient and ‘green’ gas turbines (GT). A GT is composed of a compressor, a combustor and a turbine, and it is driven by combustion, heat transfer, thermal behaviour of the solid parts, acoustics and noise generation and mechanical vibration. GT optimization is therefore a complex multi-physics, multi-component problem, which has long been based on engineering intuition and expensive experiments and tests. Developing numerical tools and methodologies to simulate the entire GT with all physical effects is a new challenge and the overall scientific objective of the COPA-GT Marie Curie European project, involving 8 partners from research and industry. (Turbomeca, Rolls-Royce, Siemens). Such coupled simulations represent one of the most demanding challenges for High Performance Computing (HPC).

Description / Description

The proposed post-doc is devoted to the development of high-accuracy LES of industrial burners, in order to apply it to the problem of noise generation. Noise is related to small pressure perturbations which must be captured with precision in a highly perturbed flow. This requires particular and accurate numerical methods and physical models.
This work will be realized in collaboration with RWTH Aachen (group of W. Schröder), who will use the developed method for high-accuracy LES in conjunction with their own acoustic tools to study noise generation and propagation of flames and industrial burners.
