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...

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...

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...

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...

Copper Deposition in a Trench
This model demonstrates the use of moving meshes in the application of copper electrodeposition on circuit boards. In these environments, the presence of cavities or ‘trenches’ are apparent.
The model makes use of the Nernst-Planck application mode in combination with a Moving Mesh (ALE) appl...

Droplet Breakup in a T-junction
Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets. Simulating these processes can help in optimi...

Chemical Vapor Deposition of GaAs
Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface.
This example illustrates the modeling of such a CVD reactor where triethyl-gallium first decomposes, and the reaction products along with a...

A Rechargeable Lithium Battery Model – Charge and Discharge Behavior
The transient charge and discharge performance of a rechargeable Li battery is strongly dependent on the design and choice of materials.
This model allows you to investigate the behavior of a Li-ion cell based on a number of design parameters. The model simulates cell voltage, capacity, current d...

Turbulent Two-Phase Flow Benchmark
This model shows how to solve a turbulent two-phase flow problem with the k-? Turbulence Model closure model.
Industrial scale mold-filling problems often involve free-surface flows with a high Reynolds number, and a suitable turbulence model must be employed.´
Liquid water is injected into...

Ozone Combustion
This 1D example illustrates the detailed modeling of a premixed, laminar, steady-state flame where ozone undergoes combustion to form oxygen. The chemical degradation of ozone is described by seven reversible, elementary reactions.
Mass, energy and continuity equations, describing the flame, are...
