La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
An axisymmetric model of a rigid piston in an infinite baffle is used to exemplify the Exterior Field Calculation feature of the Acoustics Module. The radiation results provided by the COMSOL Multiphysics® software are compared to analytical results for the on-axis radiation ... Per saperne di più
This tutorial model is of a micro perforated plate (also known as MPP) backed by a vibrating structure. This is a typical configuration in, for example, a MEMS microphone. The vibrating structure is not modeled explicitly, but just assigned a vibration velocity. The vibrating structure ... Per saperne di più
This model demonstrates topology optimization for a problem involving acoustic-structure interaction for a sound partition problem. The objective being to reduce sound transmission for a fixed solid material fraction. The design domain is modeled with a mixed formulation using the Solid ... Per saperne di più
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 ... Per saperne di più
This tutorial demonstrates how to compute the response of an ultrasonic car parking sensor transducer coupling Pressure Acoustics, Frequency Domain, Solid Mechanics, and Piezoelectric Materials. The far-field radiation pattern of the transducer is then used as a source for a Ray ... Per saperne di più
This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component. Specifically, this example treats the case of a double-glazed window. The method used here is valid for structural components that have a small influence on ... Per saperne di più
This is the model of the acoustics in a particulate-filter-like system. Real systems, like diesel particulate filters (DPFs), are designed to remove/filter soot (diesel particles) from the exhaust of diesel engine vehicles. The porous medium in such systems are typically structured with ... Per saperne di più
Anechoic coatings are used on submarines to reduce sonar reflections. This model calculates the reflection, absorption, and transmission properties of an anechoic coating on a steel plate. The calculated results from this sub-model can be used in larger system scale models, for example, ... Per saperne di più
We have all noticed the Doppler effect when an ambulance passes by with its sirens blaring. The siren’s pitch suddenly drops the moment the ambulance starts moving away from you. Another effect you can notice is how the siren’s sound is very loud when nearby, but as soon as the ... Per saperne di più
The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker. This model combines five Bessel panels in the same pattern to approximate a purely radial sound field. The speakers are driven with different ... Per saperne di più
