 Viscous Heating in a Fluid DamperFluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical... Journal BearingJournal 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... Swirl Flow Around a Rotating DiskSwirl flow is an application that involves steady rotational flow around an axis. Rather than modeling this process in 3D, COMSOL Multiphysics provides a 2D axisymmetric interface where the flow in the rotational direction is still... Turbulent Two-Phase Flow BenchmarkThis model shows how to solve a turbulent two-phase flow problem with the k-epsilon Turbulence Model closure model. Industrial scale mold-filling problems often involve free-surface flows with a high Reynolds number, and a suitable... 1D Plane Slider bearingThis 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. 1D Step BearingThis 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. Bending PipeThis model studies the fluid flow through a bending pipe in 3D for the Reynolds number 300 000. Because of the high Reynolds number, the k-epsilon turbulence model is used. Calculations with and without corner smoothing are performed. The... Diverging DuctWhen 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... Inclined ScreenThis 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. NACA 0012 AirfoilThis model simulates the flow around an inclined NACA 0012 airfoil at different angles of attack using the SST turbulence model. The results show good agreement with the experimental lift data of Ladson and the pressure data of Gregory...
