Cooling and Solidification
In this model, continuous casting processing of a metal rod from melted to solid state is modeled.
The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to solid. This phase change causes momentum changes, latent heat release and a variation in ph...

Fluid-Structure Interaction in Aluminum Extrusion
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with a very high...

Shell-and-Tube Heat Exchanger
In this model, you will study a part of a shell-and-tube heat exchanger, where hot water enters from above. The cooling medium flows through the tubes that, in this model, impose a constant temperature at the walls. Furthermore, the tubes are assumed to be made of stainless steel and the heat flux i...

The Action of Boiling Water from Two Adjacent Nozzles
Boiling flow is an example of phase transition initiated by raising the temperature of a liquid above its saturation temperature. It is possible to accomplish this in many ways; in this example by applying an external heat flux to a solid surface in contact with the liquid.
There are three disti...

Absorbed Radiation (SAR value) in a Human Head
The increasing use of wireless equipment has also increased the amount of radiation energy to which human bodies are exposed. A common property that measures absorbed energy is the SAR value, (specific absorption rate) to determine the amount of radiation that human tissue absorbs.
The human head...

Forced Convection Cooling of Horizontal Circuit Board
In this suite of models, temperature distribution and fluid flow field is modeled with the General Heat Transfer and the Non-Isothermal Flow application modes. By modeling the fluid flow and heat transfer simultaneously the convective transfer is described very accurately. The results are analysed a...

Free Convection in a Light Bulb
This model treats the free convection of argon gas within a light bulb. It shows the coupling of heat transport (conduction, radiation and convection) to momentum transport (non-isothermal flow) induced by density variations caused by temperature.
COMSOL Multiphysics model makes it possible to de...

Friction Stir Welding of an Aluminum Plate
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined.
In this model, two aluminum plates are joined by generating friction heat with...
