Аннотация

The results of calculations and measurements of the annular nozzle thrust force in a turbulent outflow regime of high-temperature combustion products are presented. Calculations are carried out on the basis of the Favre-averaged Navier–Stokes equations and the Boussinesq approximation for describing the processes of turbulent transfer. The analysis of exhaust nozzle form of annular device with internal deflector on the value of developed thrust is performed. By results of comparison of calculated and corresponding measured values of annular nozzle thrust it is performed validation of calculated model. It is established, that in the cavity of the inner deflector a “stationary” turbulent regime with high values of the turbulent transfer parameters is established.
