The acoustic attenuation and performance analysis for blast flow field inside a silencer is
investigated. In this regard, a silencer system is designed to reduce the exhaust noise. The …

A versatile unit cell for metamaterial-based mufflers that can be mounted in a limited space
is proposed and optimized without increasing their size to reduce duct noise in the low …

We propose an optimal silencer design method using the backpropagation of an artificial
neural network (ANN) model and the generative design technique. The noise attenuation …

A deep-learning-based generative design method is proposed to improve the frequency-
dependent characteristics of a reactive silencer, and it has been validated both numerically …

The progressive increase in the number of automobile transport inevitably leads to both
environmental and acoustic pollution. In this regard, the world is adopting restrictive …

Nowadays, the automotive industry is focused on weight and size reduction. Main
advantage of this weight and size reduction are improving the fuel economy. The specific …

Abstract Evaluation of acoustic characteristics of an internal combustion engine (ICE) takes
into account its capability to reduce gas dynamic noise from exhausted gases as well as the …

mufflers are generally designed to attenuate or absorb the noise produced by engines,
power plants etc. The reason that nowadays design of mufflers has grabbed the attentions is …

This paper is the results of an undergraduate final term project. The aim of project was to
investigate the passive noise reduction methods in mufflers. Also, another aim of this study is …

It is known that nonlinearities in the friction-velocity curves of dry friction may lead to
instability of the steady frictional sliding, namely, friction-induced vibration. Therefore, stick …
