The use of the hybrid RANS/ILES approach for the investigation of three-dimensional separated turbulent flows in curvilinear diffusers
D. A. Lyubimov Central Institute of Aviation Motors, State Scientific Center of Russian Federation, Moscow
Abstract:
The hybrid RANS/ILES approach is used for the investigation of turbulent separated flow in curvilinear annular diffusers with the area ratio of 2.04 and 2.7. The effect of geometry on the loss of symmetry of flow in an axisymmetric annular diffuser is considered. The effect of pressure difference in the diffuser on the flow and on the characteristics of turbulence in this diffuser is investigated. The effect of nonuniform total pressure at the channel inlet on the distribution of parameters in the outlet section of the diffuser is determined. The loss of total pressure in diffusers is determined for all of the considered modes. The accuracy of the results is confirmed by comparison with the experimental data available for these diffusers.
