Sound produced by entropic and compositional inhomogeneities
Combustion noise is central to several efforts to curb aircraft emissions. Indeed, acoustic waves originating in the combustor are a major contributor to aircraft noise. Moreover, they can act as a trigger for thermoacoustic instabilities, the consequences of which may range from decreased …

Indirect noise in non-isentropic flows
… of the combustor generates indirect combustion noise. Indirect noise is a large contributor to aircraft engine noise, therefore, it is an important aspect of the design of an aircraft engine. It is essential to model indirect noise because it can add to the thermoacoustic feedback and contribute …
