This model example shows how to model nonlinear propagation of 1D finite-amplitude Acoustic waves in fluids using Acoustics Module of COMSOL Multiphysics. The model is based on the 2nd order Westervelt equation. The one dimensional nonlinear wave equation is solved in the time domain by ... 詳細を見る
A 3D model of an acoustic trap in a glass capillary actuated by a piezoelectric transducer. The system is actuated by an oscillating electric potential across the piezoelectric transducer inducing mechanical vibrations in the solid and an acoustic pressure field in the fluid. The heat ... 詳細を見る
This model performs a transient analysis of the temperature through a house wall. The wall is formed of different layers corresponding to the structure, insulation and plaster. On the exterior and the interior, the wall is exposed to thermal radiation and convective cooling. The results ... 詳細を見る
This tutorial shows how to include local nonlinear effects when simulating the acoustics of an exponential horn. Nonlinear effects become important when an acoustic horn is used for high amplitude signaling. The Nonlinear Acoustics (Westervelt) Contributions feature available for the ... 詳細を見る
Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model ... 詳細を見る
This tutorial model shows how to model a microspeaker located in a smart phone including the radiation through and interaction with the acoustic port that connects to the exterior. The model demonstrates a linear frequency domain analysis as well as a nonlinear time domain analysis. A ... 詳細を見る
A 3D model is used to simulate the cooling of a bevel gear from an austenitic state. Phase material properties and phase transformation data are imported into the model. The final phase composition and the residual stress state are computed. Phenomena such as thermal strains, phase ... 詳細を見る
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, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... 詳細を見る
Coplanar waveguide (CPW) bandpass filters can be designed using interdigital capacitors (IDCs) and short-circuited stub inductors (SSIs). This is a very efficient manufacturing method for producing bandpass filters, which can readily be implemented on a GaAs wafer. The Coplanar ... 詳細を見る
This model shows how to use the scattered field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite size phononic crystal. The transmission tends to zero in the frequency range corresponding to P- and S-wave band gaps, as ... 詳細を見る
