Hydraulic pumps are a positive displacement pump whose working principle causes
inherent output flow pulsation. Flow pulsation produces pressure pulsation when …

The tail pipe noise from a commercial automotive muffler was studied experimentally and
numerically under the condition of wide open throttle acceleration in the present research …

The 3D time-domain computational fluid dynamics (CFD) approach is used to calculate the
acoustic attenuation performance of perforated tube silencers without and with flow. For the …

The pressure waves escape from the engine exhaust with a high velocity producing an
offensive exhaust noise. A properly designed exhaust silencer is helpful to reduce exhaust …

Transmission loss (TL) is often used to evaluate the acoustic attenuation performance of a
silencer. In this work, a three‐dimensional (3D) finite element method (FEM) is employed to …

As major equipment for implementing technological process, Shell-and-Tube Heat
Exchangers are widely used in modern industries. Because the noise propagation in …

Compared to the linear frequency domain method, the transient Computational Fluid
Dynamics (CFD) method is more effective when analyzing the effect of complex flow in the …

In this work we present the research on pressure loss for a muffler with CFD method.
Through using CFD technique, at a certain engine velocity, the flow field of a muffler is …

This paper proposes an approach to investigating the effect of different temperatures and
flow velocities on the acoustic performance of silencers in a more accurate and meticulous …

The acoustic attenuation and acoustic pressure levels of a single-cylinder diesel engine are
computed using COMSOL Multiphysics tool to evaluate the performance of the reactive …
