Abstract:
The results of supersonic jet noise prediction are represented. Numerical simulation
procedure includes two main stages. At the first stage, a steady flow field for turbulent
supersonic jet is calculated with the help of Reynolds averaged Navier–Stokes equations
closed by $k-\varepsilon$ turbulence model. At the second stage, the data on mean flow parameters and turbulent characteristics obtained at the previous stage are used at solving the
linearized Navier-Stokes equations with specially constructed source terms. Kinetically
consistent finite difference (KCFD) schemes are taken as a basic numerical algorithm.
