This example models 3D supersonic flow, including the effect of a shock, in a straight channel with a small obstacle on one of the walls. As the flow hits the obstacle, shock waves are diffracted from the obstacle and walls of the channel. The propagating shock waves form a pattern in ... Mehr lesen
Experiments on dry and wet soil samples are performed to understand their behavior under different loading conditions. In this example, the Extended Barcelona Basic (BBMx) soil model is used to simulate the wetting and drying paths in partially saturated soil samples under cyclic ... Mehr lesen
An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, ... Mehr lesen
Permanent magnet bearings are used in turbomachinery, pumps, motors, generators, and flywheel energy storage systems, to mention a few application areas; contactless operation, low maintenance, and the ability to operate without lubrication are some key benefits compared to conventional ...

In this example, a rotor supported on two hydrodynamic bearings is analyzed. An eccentric disk located between the two bearings causes the rotor to whirl. One of the bearings is misaligned with the axis of the rotor. The Beam Rotor with Hydrodynamic Bearing interface in the ... Mehr lesen
Just like optical lenses focus light, electric and magnetic lenses can be used for focusing beams of charged particles. This COMSOL Multiphysics model shows the path of B5+ ions passing through a focusing system of three magnetic quadrupoles. Each of the quadropoles focus the beam of ... Mehr lesen
This model shows how to simulate the time-dependent adsorption and desorption of water in a vacuum system at low pressures. The water is introduced into the system when a gate valve to a load lock is opened and the subsequent migration and pumping of the water is modeled. Mehr lesen
This tutorial demonstrates how to use stationary polarization data to perform parameter estimation of a polymer electrolyte membrane fuel cell (PEMFC) model. The model, defining a 5-layer membrane electrode assembly (MEA) is two-dimensional and includes electronic and ionic charge ... Mehr lesen
For several high-precision applications, especially in hydraulic systems and fuel injectors, micro bores are needed. In most cases the shape of the injection hole, especially the edge rounding, has a significant influence on the atomization of fluids and therefore on the combustion ... Mehr lesen
When analyzing rotors, it is common that bearings are modeled through their effective dynamic coefficients about a static equilibrium position. This model illustrates how to compute such coefficients for a cylindrical journal bearing. The bearing length is kept much smaller than its ... Mehr lesen
