Large-eddy Simulation in Hydrophysical and Hydroacoustic Problems

Volkov K., Emelyanov V., Kurova I.

Applications of large-eddy simulation (LES) technique to the solution of problems of hydrophysics and ‎hydroacoustics are considered. Solutions of some model problems (free mixing layer, free sub-sonic non-‎isothermal turbulent jet flowing out of circular nozzle into submerged space, and aero-optical effects in ‎turbulent flows) are presented. The results obtained are compared to the data calculated with the numeri-‎cal solution of the Reynolds-averaged Navier–Stokes equations and equations of the k–ε turbulence ‎model, as well as to the available experimental data. The conclusions related to the perspectives of use of ‎this technique in the problems of hydrophysics and hydroacoustics are made.
