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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
