  • Leontiev M.K., Kutakov M.N. Selecting a squeeze film damper model for solving rotor dynamics gte problems
    Vestnik of Samara University. Aerospace and Mechanical Engineering. 2017. V. 16, no. 3. P. 81-93.
    Selecting a SFD model Various standard mathematical squeeze film damper (SFD) models, which can be applied for solving rotor dynamics problems of gas turbine engines (GTE), are presently available. Accuracy of the whole simulation is ultimately affected by the choice of a certain SFD formulation, which depends on many factors Ð geometry parameters, oil supply method, oil inlet pressure, operating conditions etc. The present contribution suggests some recommendations for selecting a particular mathematical SFD model and compares the simulation results obtained with different SFD formulations. To this end a point rotor system is numerically analyzed with the aid of the DYNAMICS R4 (www.alfatran.com) software.
