The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... En savoir plus
This is a model of a simple thermoacoustic engine that includes a thermal stack to convert thermal energy to acoustic energy. The model is set up using two approaches: 1) Using a linear perturbation (acoustic) approaches solving the fluid motion with the Thermoviscous Acoustics, ... En savoir plus
This model demonstrates three different ways to find the eigenfrequencies of a rectangular metallic cavity. The first method uses an eigenfrequency study step together with the Electromagnetic Waves, Beam Envelopes interface. Here, it is important to define a wave vector for the physics ... En savoir plus
These two example models demonstrate how state variables (new in COMSOL Multiphysics® version 5.5) can be used to define and use history-dependent variables. Learn more in the accompanying blog post: "How to Use State Variables in COMSOL Multiphysics®" En savoir plus
Tutorial model investigating a set of two competing reactions. The model demonstrates the natural modeling strategy for reaction engineering in COMSOL Multiphysics®. That is, how to go from chemical equations to space-dependent models of reacting flow with a minimum of work. En savoir plus
The aerodynamic properties of a wing, propeller, or turbine blade are to a large extent determined by the precise shape of the airfoil that is used. The NACA Airfoil Optimization application computes the two main aerodynamic properties (the lift and drag coefficients) of a fully ... En savoir plus
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies. The main advantage of DBRs over ordinary metallic mirrors is that DBRs can be engineered to have custom ... En savoir plus
This model describes the evaporation of a droplet that consists of concentrated solution of acetone and water. It accounts for the coupled phenomena of chemical species transport and heat transfer over phase boundaries (liquid-gas boundary) as well as for multiphase flow. The droplet ... En savoir plus
See how to generate a mesh from scanned data via two different workflows. For both examples, the data file is imported in an Interpolation function. In the first workflow, the data is applied on a Grid dataset and a Filter dataset is used to filter out the data to represent the femur. ... En savoir plus
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... En savoir plus
