The Measurement of Ammonia in Lean Combustion Exhaust Gases [PDF]
Combustion Science and Technology, 1982 Abstract Measurements of ammonia emissions in the exhaust gases of a lean-burning laboratory combustion tunnel were made by means of a variety of measurement techniques, using a common sampling method to allow meaningful intercomparisons. Combustion parameters varied from cold flow conditions to a range of equivalence ratios, sampling temperatures, and

Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame [PDF]
, 2012 This paper investigates one issue related to Large Eddy Simulations (LES) of self- excited combustion instabilities in gas-fueled swirled burners: the effects of incom- plete mixing between the gas injection and the combustion chamber.

Numerical analysis of reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion [PDF]
, 2009 The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations (DNS) of three-dimensional, turbulent Bunsen flames with reduced methane-air ...
