Urea-SCR Technology for deNOx After Treatment of Diesel Exhausts

Abstract

This chapter describes the numerical models adopted for the simulation of the internal flows inside exhaust systems of internal combustion engines, with particular focus on the part of the system upstream of the catalytic converter. Particular attention is paid to the modeling of the dosing system, which requires a correct numerical description of the spray evolution inside the gas stream, and its subsequent interaction with pipe walls (or eventual mixing device) and the dynamics of the liquid film. The simulation of all these processes is mandatory when an optimization of the exhaust systems is addressed in order to improve the abatement efficiency of the SCR system.
