Turbocharger Supported on Floating Ring Bearings
Application ID: 67811
In this model, a turbocharger supported on two floating ring bearings is studied. The film forces on the ring cause it to rotate within the bearing. In steady state, the ring rotates at a constant angular speed and the torque on the ring due to the inner and outer films are balanced.
The Beam Rotor interface is used to model the turbocharger rotor which is coupled with the floating ring bearing through multiphysics couplings. The inner and outer films in the floating ring bearings are connected through six channels in the ring.
The results include stress in the rotor, pressure distribution in the bearing, speed variation of the ring, total moment on the ring, and flow rate through ring channels.
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.
