Fuel Tank Vibration new

This model analyses the frequency response of a fuel tank partially filled with fluid. The tank is submitted to a vertical acceleration. Two modelling methods are considered to represent the fluid; a traditional method of smearing the mass of the fluid through the wetted surface of the ... En Savoir Plus

Absorptive Muffler with Shells

This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the ...

Ear Canal Acoustics

In this tutorial model, the acoustics of the human ear canal are investigated. The output includes the input impedance and the transfer impedance, as well as the level transformation from the entrance to the eardrum. The geometry of the ear canal used is based on measurements from test ... En Savoir Plus

Underground Train Induced Noise in Urban Buildings

Underground train grid spans large areas under London, Paris, New York and other cities. The building regulations require strict noise standards and failure to comply with them may results in significant losses in the market prices of the developments. Train induced noise has therefore ... En Savoir Plus

Diesel Particulate Filter Analysis Using an Acoustic Transfer Matrix

Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... En Savoir Plus
