Soot and NOx Formation in a Stationary Turbulent Combustor
نویسندگان
چکیده
On the basis of the stochastic reactor model Partially Stirred Plug Flow Reactor (PaSPFR) a model is developed that accounts for soot and NOx formation in the distributed combustion regime. This is done by means of the joint composition probability density function (PDF). The composition vector consists of the species mass fraction in the gas phase, enthalpy, and four moments of the soot particle size density function (PSDF). The gas phase reactions are modeled by a detailed chemical mechanism containing 104 chemical species. Micromixing effects are described by the IEM model for the molecular diffusion term in the PDF transport equation. This model is then used to calculate the second stage of a bench scale combustion unit. For typical operating conditions of the reactor soot and NOx formation is analyzed.

Particulate matter (soot aerosol or carbon black) emissions from combustion systems have adverse effects on human health and the environment. Soot is a major contributor to the total radiation heat loss in propulsion systems. Soot aerosols in the atmosphere have significant positive radiative forcing that contributes to global warming because of strong absorption of sunlight by soot. As compare...
