The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This example models a small reverse osmosis water desalination unit. The unit consists of a spirally wound semi-permeable membrane through which the water is forced under high pressure. The membrane retains the salt, such that on the permeate side fresh water is produced and on the ... Read More
Turbulent flow, SSG-LRR interface is used to analyze fully developed turbulent flow in an axially rotating pipe and in a swirling jet emanating from such a pipe. The resulting flow pattern in the pipe is characterized by slower-than-solid-body rotation. Axial velocity of the swirling jet ... Read More
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 ... Read More
You can use assembly meshing to reduce the number of mesh elements in your model, which is especially useful for conjugate heat transfer simulation in cases where the fluid domains can be handled with swept mesh. These models demonstrate how to use form assembly and discontinuous meshes ... Read More
Active aerodynamics systems actuate components on a vehicle dynamically to improve fuel efficiency, optimize cooling, and enhance stability. A drag reduction system (DRS) is an example of an active aerodynamic technology, which is often used in Formula 1® cars to overtake other cars ... Read More
Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ... Read More
To understand the risk of coagulation and blood clot formation in an abdominal aortic aneurysm (AAA), modeling and simulation can be used to study the blood flow through the AAA. In this example, blood is modeled as an Oldroyd-B fluid. While this is a generic example, if instead using ... Read More
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Rayleigh-Bénard's convection cells is a classic in fluid dynamics. We present here two different approaches for computing the critical Rayleigh number above which the cells form. Read More
The TSSG process, namely Top-Seeded Solution Growth, is a method used to grow SiC single crystals. It has the advantages of lower growth temperature and high crystal quality. This model introduces the simulation method of the TSSG process, obtains the temperature distribution of the ... Read More
