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
This is a model exemplifying how fluid-structure interactions can be modeled using COMSOL Multiphysics. Viscous forces and the system’s pressure impose forces to the surface of a structure. The deformation in the soft structure is not small and the fluid regime will therefore dynamically change. T...

Thermal Decomposition of a Chemical through a Parallel Plate Reactor
This model investigates the unimolecular decomposition of a chemical passing through a parallel plate reactor. The heat sensitive compound is present in a water solution.
After entering the reactor, the liquid first experiences expansion, due to a step-change in geometry at the bottom plate. Befo...

Blood Vessel
This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel wall...

Fluid-Structure Interaction with Two Fluid Phases
The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary Lagrangian-Eulerian (ALE) technique along with the Two-Phase Flow, Ph...

A Transient Analysis of Freeze-drying
Freeze-drying, or lyophilization, is a process for drying heat-sensitive substances such as foods, blood plasma, and antibiotics. The wet substance is frozen and then through sublimation ice or some other frozen solvent is removed in the presence of a high vacuum.
This example models the process...
