Abstract
Tilting Pad Journal Bearings (TPJBs) are widely used in the turbomachinery field due to their superior dynamical performances, but their operation involves several different physical phenomena. In this research work the authors propose an innovative 3D ThermoElastoHydroDynamic (TEHD) model for the analysis of TPJBs behaviour developed and experimentally validated in cooperation with General Electric Nuovo Pignone: the model is able to perform a nonlinear transient coupled analysis taking into account fluid dynamical, thermal and elastic effects and reaches a good compromise between the accuracy of the results and the computational efficiency.
