Title
Acoustic Analysis and Design of Short Elliptical EndChamber Mufflers (SpringerBriefs in Applied Sciences and Technology),Used
Delivery time: 8-12 business days (International)
This book presents a threedimensional analysis of acoustic wave propagation in an elliptical waveguide, and applies the equations and concepts to design axially short elliptical endchamber muffler configurations which are an important component of a complex multipass muffler used in a modernday automotive exhaust system. A general solution of the Helmholtz equation in elliptical cylindrical coordinates is presented in terms of the Mathieu and modified Mathieu modal functions. This is followed by the tabulation and analysis, for the first time, of the nondimensional resonance frequencies of the transverse modes of a rigidwall elliptical waveguide for a complete range of aspect ratio. The modal shape patterns of the first few circumferential, radial and crossmodes are examined with particular attention to the pressure nodal ellipses and hyperbolae. An analytical formulation is then outlined for characterizing a singleinlet and singleoutlet elliptical muffler with the inlet located on the end face and the outlet located either on the end face or sidesurface. The ensuing chapter is devoted toward analyzing the Transmission Loss (TL) performance of different short endchamber mufflers, namely (a) the straightflow configuration having ports located on the opposite face, (b) the flowreversal configuration with ports located on the same end face and (c) configuration with inlet port on the end face and outlet on the side surface. Design guidelines are formulated in terms of the optimal location of inlet and outlet ports which suppresses the deteriorating influence of certain higherorder modes, thereby delivering a broadband TL performance. Directions for future work are discussed toward the end.In summary, this book is a onestop solution for a practicing automotive engineer designing mufflers, for an applied mathematician studying wave propagation in elliptical geometries, and also as a niche area within noise control engineering.
