Optimal Muffler Design

Computer Aided Design on Single Expansion Muffler with Extended Tube under Space Constraints

The optimization approach of maximal STL (sound transmission loss) and muffler dimension under space constraints within a building or machine room is fully addressed throughout the graphic analyses as well as the computer-aided numerical assessments in this paper. The primary set of design data is derived by the computer graphic analysis on sensitivity, and the successive algorithm of iteration...

Study on Acoustic and Fluid Characteristics of Exhaust Muffler

Engine noise is mainly from exhaust noise. Without adding muffler, at a certain speed, the noise up to 100 decibels. Reduce engine exhaust noise, and to high-temperature exhaust gas can be safely and effectively. Muffler as part of exhaust pipe, should ensure that the exhaust flow, resistance and sufficient strength. This research takes an exhaust silencer as a study object, and a muffler sound...

Design Of The Suction Muffler Of A Reciprocating Compressor

The suction muffler of a reciprocating compressor is used for reducing a noise produced by pressure pulsations. According to the shape, the suction muffler is classified into one-chamber type, two-chamber type, Helmholtz-resonator type, pipe-resonator type, and so on. These mufflers are used according to the characteristics of the frequency of compressor noise. In this study, four pole paramete...

Fluid Chamber Membrane

A new format for solid-phase immunoassays has been developed in which a monoclonal antibody-coated membrane, incorporated into a cylindrical, disposable device, regulates sample and reagent delivery. We illustrate the method with a two-site, immunoenzymometnc assay that can detect human choriogonadotropin at less than 50 mt. units/L (4 pg/L) in urine and less than 25 mt. units/L (2 j.tg/L) in s...
