Scattering of an entropy disturbance into sound by a linear cascade of turbine stator blades
… known that modern turbofan engines produce more noise from their exhaust than can be accounted for by jet noise alone. Part of the extra noise coming from the exhaust of the engine is associated with the combustor. Apart from direct combustion noise, the combustor is known to have an indirect …

Indirect noise in non-isentropic flows
… makes the combustor susceptible to unsteady combustion. Along with improper mixing and air cooling, the unsteady combustion process gives rise to flow inhomogeneities. The acceleration of these inhomogeneities in the nozzle downstream of the combustor generates indirect combustion noise. …
