Abstract

large eddy simulation (LES) approaches are widely used to study flame structures and dynamics in gas turbine combustor. This project is motivated by the public concerns on emission of pollutants (soot, NOx, CO, and unburned hydrocarbons) from fossil fuel combustion. We will do some simulation at LEAN premixed condition to reduce the NOx emission and give some principles. The goals of this project are (i) to achieve improved understanding of the physical and chemical processes in overall fuel-lean combustion processes, (ii) to generate reliable database for validating simulation models for analysis of the class of combustion problems.
