  • A three–dimensional CFD approach for prediction of noise reduction of mufflers without mean flow

    A CFD approach, in which the full equations are solved in the time domain, is proposed to calculate noise reduction of a cleaner and a complex exhaust muffler without mean flow. First, two modelling approaches are used to deal with the outlet boundary and to calculate noise reduction of the cleaner without a filter element. The calculated results agree quite well with measurements. Further, the ...

  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • Retrofitting diesel engines: reducing the emissions of our ideal power source

    Over the past several years, Avogadro Environmental has been working with a number of clients to develop proactive environmental programs as part of their EPA Performance Track and ISO 14001 management systems.  Many client companies that are proactively implementing measures to reduce their environmental footprint are looking for ideas.  Diesel engine retrofits for off-road stationary and mobile ...

  • Innova`s race against time; the sonic mystery

    What began as a puzzling mystery in the semi-arid scrub-land of Colorado, ended as a race against time for the acoustic specialists of INNOVA (formerly ATCO Noise Management). The Olathe Compression Station, operated by Kinder Morgan’s TransColorado Gas Transmission, is located on a plateau in isolated, canyon-cut Colorado countryside, three km from the nearest ...

  • Industry Takes Shape: Why Digesters Make Dollar Sense Now

     THIRTY years ago, when I was a college student studying ways to convert manure to electricity, we speculated that the 1970s would be the decade of the innovators, the 1980s for the launch of operating projects, and the 1990s when the mainstream adopted the technology. Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...
