Although the CHARLES solver was developed to tackle problems like high - fidelity jet engine simulation and
supersonic jet noise prediction, it had never been applied to predict combustion dynamics in a configuration as complex as a GE gas turbine combustion system.
But while they're good at predicting
supersonic sound sources, they have a hard time predicting all the components of subsonic
jet noise, especially in the sideline direction, or perpendicular to the exhaust stream.
