Acoustic Source Characterization Of The Exhaust And Intake Systems Of I.C. Engines
(2010-07-15)For an engine running at a constant speed, both exhaust and intake processes are periodic in nature. This inspires the muffler designer to go for the much easier and faster frequency domain modeling. But analogous to ... -
Analysis Of Multiply-Connected Acoustic Filters with Application To Design Of Combination Mufflers And Underwater Noise Control Linings
(2008-10-01)This thesis endeavors towards developing various concepts employed in analysis and design of acoustic filters for varied applications ranging from combination mufflers for automobiles to complex networks of gas carrying ... -
Asymptotic Analysis Of The Dispersion Characteristics Of Structural Acoustic Waveguides
(2010-04-12)In this work, we study the coupled dispersion characteristics of three distinct structural-acoustic waveguides, namely: -(1) a two-dimensional waveguide, (2) a fluid-filled circular cylindrical shell and (3)a fluid-filledelliptic ... -
Flow Acoustic Analysis Of Complex Muffler Configurations
(2013-06-21)A theoretical study has been carried out on different methods available to analyze complex mufflers. Segmentation methods have been discussed in detail. The latest two port segmentation method has been discussed and employed ... -
Resonances and beats in nonlinear structural acoustic waveguides
In this thesis that is entirely analytical in nature, nonlinear wave propagation in various structural-acoustic waveguide geometries is studied. The waveguides considered include a circular cylindrical waveguide with a ... -
Sound Radiation from Rectangular Panels with Rectangular Cut-out/s
This is largely an analytical investigation and the objective of this study is to compute sound power radiated from rectangular panels that are placed in an infinite baffle (or a rigid wall) and that have rectangular ...
