Abstract:The calculation of noise generated by a jet of viscous compressible gas flowing out from a conical nozzle is considered.
The calculations used the implicit version of the LES (Implicit LES, ILES), in which the role of the subgrid turbulence model performs
numerical dissipation used finite-difference scheme. The distributions of the gas-dynamic and acoustic characteristics of the jet upon
changing the conditions of its outflow are discussed. The analysis of the modal composition of the received noise is carried… Show more
