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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.

Thermal Stress Analysis of a Turbine Stator Blade

The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore be carefully designed to be able to withstand thermal stresses, vibrations and loads asserted by the fluid rushing through the ... Read More

Radiative Cooling of a Glass Plate

When producing glass, the glass melt is cooled down through radiation to form the final shape, subjecting it to stresses. Numerical treatment of radiative heat transfer, using the Radiative Transfer Equation (RTE), helps to optimize this process. COMSOL Multiphysics provides three ... Read More

Sun's Radiation Effect on Two Coolers Placed Under a Parasol

The Parasol and Solar Irradiation app illustrates how to model the thermal effects of the sun as an external radiative source. You can use the app to investigate the solar irradiation on a beach with two coolers placed in different positions under a parasol. You can vary the length of ... Read More

Viscous Heating in a Fluid Damper

Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon ... Read More

Radiative Heat Transfer in a Utility Boiler

This model uses the discrete-ordinates method (DOM) to analyze the radiative heat transfer in a utility boiler with internal obstacles. DOM is one of the most useful radiation models for prediction of radiative heat fluxes on the furnace walls of a combustion chamber. With this model, ... Read More

Flat Heat Pipe

Heat pipes are used in a wide range of applications for efficient cooling, for example in microelectronic systems, computer internals, and for large cooling devices in spacecraft industry. It combines the principles of heat conduction and phase change to get extremely efficient heat ... Read More

Modeling Laser Beam Absorption in Silica Glass with Beer-Lambert Law

This tutorial shows how to use the Radiative Beam in Absorbing Media interface (Heat Transfer Module) to model the attenuation of a laser light going through a sample of silica glass, and the heat source generated by the absorption. Read More

Turbulent Flow over a Backward-Facing Step

The backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. In this case, the flow is subjected to a sudden increase of cross-sectional area, resulting in a separation of flow starting at the point of expansion. Spatial ... Read More

Inline Induction Heater

Ferritic stainless steels have become more and more popular in the food industry because of their relatively low and stable price and due to the absence of nickel in their components. Their resistance to corrosion can be improved by adding chromium or molybdenum, and their magnetic ... Read More

Buoyancy Flow in Air

This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. Read More
