This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Mehr lesen
In this classical benchmark model, a spherical scatterer is placed in a plane wave background field. When the sphere is modeled as sound hard, the problem has an analytical solution. The model compares the results using the Pressure Acoustics, Boundary Elements interface with the ... Mehr lesen
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 ... Mehr lesen
This example models the radiation of fan noise from the annular duct of a turbofan aeroengine. When the jet stream exits the duct, a vortex sheet appears along the extension of the duct wall due to the surrounding air moving at a lower speed. The near field on both sides of the vortex ...

Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Mehr lesen
The models simulate the working mechanism of traveling wave thermoacoustic engines. Similary to the standing wave engines, the traveling wave engines make use of the coupling between the fluid motion and the temperature change experienced by the fluid to generate acoustic energy. ... Mehr lesen
Dieses Modellbeispiel zeigt, wie Sie die nichtlineare Ausbreitung einer zylindrischen Welle mithilfe dem im Acoustics Module von COMSOL Multiphysics verfügbaren Physik-Interface Nonlinear Pressure Acoustics, Time Explicit modellieren. Das Interface implementiert das System der ... Mehr lesen
This model demonstrates how to compute the acoustic properties of an acoustic liner with a grazing flow. The liner consists of eight resonators with thin slits. The background grazing flow is at Mach number 0.3. The sound pressure level above the liner is computed and can be compared to ... Mehr lesen
Acoustic droplet ejection is a non-contact, highly controllable method for liquid handling emerging in applications such as printing, biomedical, semiconductor assembly, and mass spectroscopy. The modeling approach assumes separation of acoustic and flow time scales. First, a focused ... Mehr lesen
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... Mehr lesen
