One-Family House Acoustics

This model shows an application of the Acoustic Diffusion Equation physics interface. The acoustics in a two-story one-family house consisting of 10 rooms is analyzed. The steady state sound pressure level and energy density distributions are analyzed for a monopole source located in ... 詳細を見る

Transient Analysis of a Printed Dual-Band Strip Antenna

A wideband antenna study, such as an S-parameter or far-field pattern analysis, can be obtained by performing a transient response analysis and a time-to-frequency fast Fourier transform (FFT). This model runs a time dependent study first and then transforms the dependent variable, the ... 詳細を見る

Radiative cooling

Because the atmosphere is nearly transparent to wavelengths in the range 8 to 13 µm (atmospheric window) for a clear sky, it is possible to cool down a surface even during a sunny day. This model compares the temperature distribution on a concrete block exposed to ambient and solar ... 詳細を見る

Electrochemical Impedance Spectroscopy in a Fuel Cell

A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... 詳細を見る

Underwater Ray Tracing in a 2D Axisymmetric Geometry

When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... 詳細を見る

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 ... 詳細を見る

Disc Resonator Anchor Losses

This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially ... 詳細を見る

Balanced Patch Antenna for 6 GHz

Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... 詳細を見る

Electrostatic Speaker Driver

This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... 詳細を見る

Organ Pipe Design

This app demonstrates the following: Using a Java® utility class for combining several waveforms and for playing sound Using tables for presenting results The app allows you to study the design of an organ pipe and then play the sound and pitch of the changed design. The pipe sound ... 詳細を見る
