点击翻译按钮获取中文摘要

This Small Business Innovation Research (SBIR) Phase II project will develop computational fluid dynamic (CFD) modeling technology that uses state-of-the-art techniques for modeling finite rate chemistry in chemically reacting turbulent flows with recently developed numerical methods for solving systems of non-linear equations. In Phase I an improved CFD solver was developed that used reduced chemical kinetic mechanisms to model finite rate chemistry effect and solved the resulting stiff system of partial differential equations with a matrix-free Newton-Krylov method. In Phase II two Newton-Krylov based CFD tools will be developed, one to model combustion from turbulent, diffusion flames and the second to model turbulent, pre-mixed flames.The commercial potential for this work is the electric power industry, designers and builders of commercial chemical plants, and designers of chemical process heaters and other industrial furnace applications.
