Project Description

Although the high fidelity LES model is critical to gain physical insights into the combustion instabilities for robust low-emission engine design, the cost associated with such a simulation is very expensive. To put this in perspective, typical combustion dynamics simulation of single cup configuration with 50 million mesh cells on 600 cores would take a few months to complete. These kinds of lead times significantly limit the number of cases that can be completed in a timely manner to help the design process, and inhibit significant progress for designing combustors. Demonstrating a significant decrease in simulation time using large computational resources would not only benefit the design cycle but would also incite further industry investment in high performance computing. Furthermore, the best practice/numerical tool obtained from this study can potentially shape the design process of a high-performance aero-engine, and open a new era of engine d
esign and optimization.
