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 model shows the workflow to define a transfer orbit trajectory with user defined orbit option. The direct solar, albedo, and Earth radiative thermal loads are analyzed during the transfer from low Earth orbit to geostationary orbit. Read More
Fluence rate is a key parameter for ultraviolet (UV) water purifier. It describes the amount of radiation that pathogens absorb and is then directly related to the disinfection level of the purifier. The aim of this example is to demonstrate the fluence rate calculation with the ... Read More
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... 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
When radiation occurs across a very narrow gap this is often well-approximated as radiation between infinite parallel plates. This model considers three aluminum plates separated by narrow air gaps. The model compares the classical approach, based on the Surface-to-Surface Radiation ... 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
Inside of a combustion chamber, the gas mix behaves as a non-gray medium. Such media require a lot of data and computational resources to get results across the whole spectrum. The Weighted Sum of Gray Gases Model (WSGG) proposes an approach to model the non-gray gas mix as a sum of ... Read More
A smoke exhaust duct in a building is analyzed. Radiation of a non-gray gas is accounted for with a Radiation in Participating Media interface and the Weighted Sum of Gray Gases Model (WSGG). The smoke exhaust duct consists of 25 mm plaster walls. Building codes require that the walls ... Read More
This model aims to demonstrate how a multilayer insulation can affect the temperature distribution of a satellite orbiting around the Earth. It is based on the Spacecraft Thermal Analysis model available in the Application Library. Read More
