Application of kinetically consistent finite difference schemes for turbulent supersonic jet noise prediction

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.
