Atmospheric Corrosion

This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen diffusivity and solubility are also included in the model in order to derive an expression for the limiting ...

Dielectric Resonator Antenna

A dielectric resonator placed near a radiating element can be used to increase directivity and gain. Here, a block of quartz dielectric, with additional passive metallic antenna elements, is placed above a slot antenna. The fields in and around the antenna are solved for. The far field pattern and impedance is computed and improved performance is seen.

Truss Bridge Designer

The Truss Bridge Designer app is an example of how to design a simulation tool for a class of civil engineering structures, in this case a Pratt truss bridge. Such a bridge is characterized by the diagonal beams on each side of the bridge, which all slant down and in toward the center of the span. Because of this design, the diagonal beams are subjected only to tension, while the vertical beams, ...

Electrochemical Treatment of Tumors

This model incorporates the transport and electrolytic reaction in the treatment of tumor tissue. Oxygen evolution at the anode produces protons, which lowers the pH, while chlorine production also leads to lowered pH through the hydrolysis of chlorine. One effect of a low pH is the permanent destruction of haemoglobin in the tissue, resulting in the eradication of tumor tissue. This model ...

Ideal Cloak

This model demonstrates the use of optical tracing for studying optically large gradient-index structures with anisotropic optical properties. Additionally, the model introduces a smoothing technique for handling discontinuities of refractive index on curved surfaces, which are typical in conventional optical devices such as lenses.

Rotating Channel

A lab-on-a-chip platform can be realized on a rotating disc by designing channels and other features to use the Coriolis or centrifugal forces to manipulate the flow. These forces are controlled by changing the angular velocity of the disc, so the platform is programmed by using a controlled sequence of angular velocities. In a microchannel, the centrifugal force induces a parabolic flow profile ...

1D Lithium-Ion Battery Drive-Cycle Monitoring

This application shows how a battery cell exposed to a hybrid electric vehicle drive cycle can be investigated with the Lithium-Ion Battery interface in COMSOL. This model predicts the battery behavior to make comparisons of the monitored properties. They can be used to understand the battery's behavior during the cycle better, since the model includes can calculate more than is measurable, for ...

One-Family House Acoustics Analyzer

The One-Family House Acoustics Analyzer app is used to assess noise propagation in coupled rooms inside of a two-story house consisting of ten rooms. The app determines the sound pressure level (SPL) distribution in the house based on a number of sources that are interactively placed throughout the home. It represents a classical room acoustics problem where engineers or architects want to ...

MOSFET with Mobility Models

This model shows how to add several linked mobility models to the simple MOSFET example.

Hexagonal Grating (RF)

A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths.
