The Dzhanibekov effect, also called the intermediate axis theorem or tennis racket theorem, describes the behavior of a rigid body with three distinct principal moments of inertia. This simulation app can be used to test the Dzhanibekov effect in three different geometries, including a ... En savoir plus
This model calculates the DC breakdown voltage between parallel electrodes in air using a detailed charge transport approach. It is currently one-dimensional for simplicity but can be extended to other gases and dimensions. The results closely match experimental data found in the ... En savoir plus
The dispersion curves for a fluid-filled pipe with elastic walls are computed and compared with the analytical results for a pure elastic and an acoustic waveguide, respectively. Results show good agreement and also provide insight into the dynamics of the fluid-filled pipe at low and ... En savoir plus
These models demonstrate various ways of exciting magnetic fields using the Magnetic Field Formulation interface in the AC/DC Module, an add-on to the COMSOL Multiphysics® software. To learn more about these models, see the accompanying blog post “Modeling of Excitations with ... En savoir plus
This model simulates the electrohydrodynamic (EHD) flow of a dielectric liquid around a wire electrode positioned between two parallel flat-plate electrodes. The ion transport is described using the Poisson–Nernst–Planck equations, while fluid motion is governed by the Navier–Stokes ... En savoir plus
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 ... En savoir plus
In this tutorial model, an eigenvalue analysis of a turbocharger rotor is performed. The rotor is analyzed in an unconstrained configuration, also commonly known as free–free conditions. A rotor like this is usually intended for high-speed applications, but here the analysis is performed ... En savoir plus
The NREL Phase VI wind turbine is a widely recognized standard test case in the study of wind turbine aerodynamics, and its wind tunnel test data have become an important benchmark for validating CFD numerical simulation methods. In this validation case, COMSOL Multiphysics is used to ... En savoir plus
Radial magnetic coupling between two permanent magnet rotors is modeled using the Rotating Machinery, Magnetic interface. The permanent magnets in the inner and the outer rotors are outward flux-focused and inward flux-focused to maximize the coupling torque. En savoir plus
The dipole tonal noise generated by flow over a cylinder in free space is modeled using a two step hydrodynamic/acoustic splitting method. First, the unsteady hydrodynamic flow field is calculated using the incompressible Navier-Stokes equations. Second, the Linearized Perturbed ... En savoir plus
