Journal of Mechanical Engineering| Summary: | The numerical simulation of a three-dimensional viscous flow in cascade of the axial compressor of low pressure of the gas-turbine engine is presented. Gas-dynamic calculation of a flow in the first compressor stage in non-stationary three-dimensional statement in program complex F is carried out. The two-equation differential k-ω SST Menter’s turbulence model is used. The calculation is carried out on a differential H-grid with quantity of cells more than 1,3 million in one blade channel. Distribution of speeds and pressure fields is as a result received, the main reasons nonuniformity of parameters are defined, adverse areas of a flow in the blade channel are revealed, the assessment of parameters of a flow in the grid profiles is carried out. The gas-dynamic structure of a flow has changeable character on blade height from a root to the periphery. It can be the reason of the alternating strain causing bending and torsion vibration at action of a non-stationary flow. |
