In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... En savoir plus
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, ... En savoir plus
A Chladni plate is a metal plate that is covered in sand and subjected to vibrations. At certain frequencies, the vibrations produce standing waves, resulting in sand patterns formed on the plate. The vibrations are either formed from a violin bow at the side of the plate or a wave ... En savoir plus
In this example, the transient response of a shallow foundation resting on an unsaturated soil stratum is investigated. The changes in pore suction due to water infiltration and evaporation are analyzed using the Extended Barcelona Basic soil model. The results show how the deformation ... En savoir plus
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between the Inventor® software and the COMSOL Multiphysics® software, how to modify the geometry from COMSOL Multiphysics®, and how to run a geometric parametric ... En savoir plus
Lithium-sulfur (Li-S) batteries are used in niche applications with high demands for specific energy densities, which may be as high as 500-600 Wh/kg. The chemistry is fairly complex, since multiple polysulfide species participate in the various charge transfer reactions. The chemistry ... En savoir plus
The mutual inductance between a primary and secondary single turn coil in a concentric coplanar arrangement is computed using a DC, steady-state, model and compared against the analytic solution. The induced currents in the secondary coil are computed using an AC, frequency-domain, ... En savoir plus
A contactor wedge is subject to a gravity load and is forced to slide due to a boundary load over a rigid target wedge surface, both infinitely wide. Horizontal linear springs are also connected between the left vertical boundary and the ground. This is a large sliding problem including ... En savoir plus
This model represents a test case of a flow in an elastic tube which is present in several applications. This specific case models viscoelastic flow and represents steady flow in a channel in which part of the upper wall is replaced by an elastic plate subjected to an external pressure. ...
