Abstract
Basis of numerical simulation of turbulent viscous gas flow, using the Navier-Stokes equations averaged the Reynolds (RANS-model), a static analysis of the gas turbine compressor blade was performed. The simulation of flow parameters in three-dimensional formulation was carried out. For the solution of system of the equations the iterative differential scheme was built. The initial equations are integrated numerically by use of the iterative explicit and implicit differential scheme with a second order approximation. The differential two-parametrical SST Menter's model is used as a model of turbulence. As a result, distributed pressure and velocities in the blades channel were obtained and unfavorable flow zones were identified. At the second stage, was developed algorithm by which the interrelation of the gas-dynamic and mechanical calculation program was established. As a result, distributed pressure was applied to the finite-element model of the blade and a static analysis was performed. Static calculation makes it possible to calculate the stress-strain state of the construction.
