Abstract:
1. A method of mixing an exhaust gas with a dilution gas, comprising: providing a first gas which is one of an exhaust gas and a dilution gas; providing a second gas which is the other of an exhaust gas and a dilution gas; providing a mixing chamber having a first end and a second end and substantially smooth, unobstructed, internal walls therebetween; introducing at least one substantially well-developed flow stream of the second gas into the mixing chamber at the first end; introducing a plurality of substantially well-developed flow streams of the first gas into the mixing chamber in a pattern that is symmetric with respect to both a cross-section of the mixing chamber and the at least one substantially well-developed flow stream of the second gas introduced into the mixing chamber; and discharging a combined stream of the first gas and the second gas from the mixing chamber through a convergent cone region located at the second end of the mixing chamber into a secondary mixing region.
