Влияние вакуума за последней ступенью на пространственную структуру потока в проточной части паровой турбины

Abstract

The results of numeral research of spatial structure of 3D viscous flow through the last stage of the low-pressure cylinder of 200 MW steam-turbine on the nominal regime and regimes with flow separation phenomena are presented. Research is carried out using the software FlowER. The results of calculations are compared with the experimental data. Numeral results and experimental data are in the good agreement.
