ГАЗОДИНАМІЧНА ДІЯ КІЛЬЦЕВОГО ВДУВУ НА ТЕЧІЮ В СТУПЕНІ ОСЬОВОГО КОМПРЕСОРА

The paper presents the results of an evaluation of the efficiency of the gas-dynamic effect by annular blowing on the flow in the axial compressor stage. The results of numerical investigation of the flow in the axial compressor stage are obtained using of the turbulent model SST. A comparison of the results of numerical and physical experiments showed that the error in calculating of the flow parameters during simulation was 0.09 – 0.83%. The gasdynamic effect by annular blowing on the flow in the axial compressor stage the level of hydraulic losses in the rotor ξ from 0.085 to 0.048 with the value of the coefficient of impulse blowing  с = 0.05 ... 0.08.
