Transient elastohydrodynamic squeeze film interaction

This benchmark model computes the transient pressure distribution and film height in a squeeze film bearing for lubrication in a nonconformal conjunction of a solid sphere and an elastic wall separated by a lubricant film. This model solves the benchmark case of hydrodynamic interaction between a solid sphere and a wall separated by a lubricant film, and extends the benchmark case to include ...

Journal Bearing

Journal bearings are used to carry radial loads, for example, to support a rotating shaft. A simple journal bearing consists of two rigid cylinders. The outer cylinder (bearing) wraps the inner rotating journal (shaft). The new thin-film flow user interfaces of the CFD Module enables lubrication analysis and full elastohydrodynamic simulations. This example shows the pressure distribution in ...

1D Step Bearing

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case.

Diverging Duct

When the diameter of a pipe suddenly increases, the area available for flow increases. Fluid with relatively high velocity will decelerate into a relatively slow moving fluid. Depending on the Reynolds number, this can cause turbulence and much of the excess in kinetic energy is converted into heat and therefore wasted. If the change of the cross-section is gradual, the kinetic energy can be ...

1D Plane Slider bearing

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case.

Inclined Screen

This model simulates the flow through a uniform inclined screen using the Screen feature in Single-Phase Flow physics and compares the results with an analytic solution.
