  1. 1. Development and Validation of a Numerical Tool for the Aeromechanical Design of Turbomachinery

    Författare :María Angélica Mayorca; Torsten Fransson; Damian Vogt; Eric Seinturier; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeromechanical design; turbomachinery; numerical tool; reduced order modeling; mistuning; ROM; aero-structure coupling; CFD; FEM; methods; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. LÄS MER
