About this document
Flow Induced Noise in Mufflers Simulation by Mohammadreza Naghavi is a document available to read on EtoBox.
This document summarizes a numerical study that investigated flow-induced noise in two types of mufflers using computational fluid dynamics (CFD) and computational aeroacoustics (CAA). The study used a hybrid approach of RANS simulation to obtain mean flow fields, synthetic turbulence reconstruction to generate noise sources, and a nonlinear acoustic solver (NLAS) to model near-field noise propagation. Results showed that a perforated tube muffler generated significantly lower flow noise than an expanded ch
