  • Low pressure drop mixer for radial mixing of internal combustion engine exhaust flows, combustor incorporating same, and methods of mixing
    Patent number: 8459017
    Abstract: An exhaust aftertreatment system is provided. The exhaust aftertreatment system includes a mixing arrangement for mixing flows of exhaust along a flow path. The mixing arrangement radially and angularly rearranges segments of two different portions of flow to mix the different portions of flow. The mixing arrangement initially converts a generally radially stratified temperature profile into an angularly stratified temperature profile to increase surface area between cool segments of exhaust gas and hot segments of exhaust gas. The aftertreatment system may also include a combustion chamber, a combustor housing and a combustor liner. The mixing arrangement is downstream from the combustion chamber to direct radially outward hot gas passing through the combustor liner and to direct radially outer cool gas passing between the liner and the combustor housing radially inward in an interleaving fashion.
