Validation of Dynamic Coefficients in Hydrodynamic Bearings

Application ID: 141361


In this verification example, the built-in functionality for calculating dynamic coefficients in hydrodynamic bearings is validated. The results are compared with those obtained using the finite perturbation method to ensure consistency and accuracy.

The model showcases how numerical perturbation can be performed to determine linearized dynamic coefficients of a fluid-film bearing in COMSOL Multiphysics.

This model example illustrates applications of this type that would nominally be built using the following products:
