Sound produced by entropic and compositional inhomogeneities

EO Rolland - 2018 - repository.cam.ac.uk
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 …

Low frequency generation, transmission and reflection of direct and indirect perturbations through nozzles

S Hochgreb, EO Rolland, F De Domenico - 2017 - repository.cam.ac.uk
Pressure perturbations arise in combustors from direct noise related to the change in density
in flames, as well as the indirect (entropic) noise associated with the acceleration of non …
