Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 The mathematical model, algorithm and software package was improved for aeroelastic behavior calculation of the turbomachine last stage rotor blades, taking into account nonuniform pressure behind the impeller and the non-axisymmetrical exhaust pipe. The mathematical model was developed and the numerical analysis of the viscous gas 3D flow in the axial compressor chamber was performed taking into account the partial admission and elastic oscillations of the blades. The difference scheme was improved and a program package of numerical modeling of aerothermoelasticity in the turbomachine blade rows using an implicit numerical scheme was developed. The algorithm, software package and numerical analysis of the viscous gas flows in the turbomachine flow parts, taking into account the laminar-turbulent transition in turbine and compressor blade rows, was developed.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
