Abstract

A description of the method for the e owe eld in the noise suppressing nozzle calculation is presented. The method is formulated for the Favre-averaged Navier ‐ Stokes equations. It is based on an explicit monotone second-order approximation, Godunov-type numerical scheme. The e rst set of calculations is made without turbulent and molecular viscosity being taken into account and shows that the Euler approach allows the main features of the complicated e ow in the mixer ‐ ejector nozzle to be described. Special experiments cone rm this idea and make the exactness of computational e uid dynamics results more clear.
