This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize geometry between the AutoCAD® software and the COMSOL Multiphysics® software, how to modify the geometry from COMSOL Multiphysics®, and how to run a geometric parametric ... En savoir plus
This example models the heating inside an oven with the Single Phase Flow, Heat Transfer and Surface-to-Surface Radiation interfaces. It accounts for conductive, convective and radiative heat transfer. Two computation approaches are set up: A one-way nonisothermal flow (one-way NITF) ... En savoir plus
This tutorial model illustrates the use of the nucleate boiling heat flux features to compute the transient cooling of a cylindrical rod plated with nickel, and immersed in a pool of boiling water. The temperature and heat flux results obtained with a 3D time-dependent computation, with ... En savoir plus
Droplet evaporation is ubiquitous in everyday life, and is essential in many industrial processes such as ink-jet printing, cleaning or coating of surfaces, and phase change heat transfer. In this model, a water droplet placed on a solid substrate evaporates in air. We solve the ... En savoir plus
In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic ...

Hydrodynamic bearings generate heat due to the viscous losses in the lubricant. As a result, the temperature of the rotor increases causing deformation and thermal stresses in both the rotor and the bearing housing. This example shows how to model different physical phenomena that are ... En savoir plus
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... En savoir plus
This model simulates the electrohydrodynamic (EHD) flow of a dielectric liquid around a wire electrode positioned between two parallel flat-plate electrodes. The ion transport is described using the Poisson–Nernst–Planck equations, while fluid motion is governed by the Navier–Stokes ... En savoir plus
Ponds and lakes can serve as thermal reservoirs in geothermal heating applications. In this example, fluid circulates underwater through polyethylene piping in a closed system. The pipes are coiled in a slinky shape and grouped onto sleds. The Non-isothermal Pipe Flow interface sets up ... En savoir plus
This example illustrates the principle of wet chemical etching for 2D geometry under laminar flow. The purpose of this tutorial is to examine how the copper substrate material is depleted and how the cavity shape evolves during the wet etching process. Wet chemical etching is ... En savoir plus
