Engine Coolant Properties
The engine block of a car includes a cooling jacket to remove excess heat from combustion. The cooling jacket consists of open spaces in the cylinder block and the cylinder head. When the engine is running, a coolant fluid is pumped through the jacket to keep the engine from overheating. ... En savoir plus
Aluminum Anodization
When anodizing aluminum, the surface is electrochemically altered to form an abrasive and corrosion-resistive Al2O3 film. The electrode kinetics during the process are only marginally affected as the oxide layer grows, so a stationary analysis of the current distribution is sufficient to ... En savoir plus
Rotordynamic Analysis of a Crankshaft
See how to perform a vibration analysis of the crankshaft of a 3-cylinder reciprocating engine in this tutorial model. Due to the eccentricity of the crank-pin and balance masses on the crankshaft, it undergoes self-excited vibration under rotation. The crankshaft is modeled using solid ... En savoir plus
Underwater Ray Tracing in a 2D Axisymmetric Geometry
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... En savoir plus
Buoyancy Flow in Water
This example studies the stationary state of free convection in a cavity filled with water and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, bringing the regime close to the transition between laminar and turbulent. To ... En savoir plus
Eddy Currents in a Cylinder
The eddy currents in a conductive cylinder, generated from currents passing through a surrounding coil, are studied. The skin effect in the coil is also studied. En savoir plus
Aquifer Water Table Calculation
This model demonstrates the application of COMSOL Multiphysics to a benchmark case of steady-state subsurface fluid flow and transient solute transport along a vertical cross section in an unconfined aquifer. Because of profound geologic heterogeneity, the model must estimate solute ... En savoir plus
Slot-Die Coating with Channel Defect
This is a tutorial of a slot die coating process in 3D where the channel is obstructed. The example uses a two-phase flow phase-field method with a non-Newtonian power-law fluid. The effects on the film thickness of the channel obstruction can clearly be seen. En savoir plus
Controlled Diffusion Separator
This model simulates an H-shaped micro-cell designed for diffusion-controlled separation. The cell puts two different laminar streams in contact for a controlled period of time. The contact surface is well-defined and, by controlling the flow rate, it is possible to control the amount of ... En savoir plus
In-Plane Switching of a Liquid Crystal Cell
This model demonstrates the switching capability of a liquid crystal (LC) display cell in In-Plane Switching (IPS) configuration. The Oseen-Frank model is used to solve for the LC director (optical axis) distribution when a static electric field is applied. A Weak Form PDE interface is ... En savoir plus
