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.

这个小企业创新研究（SBIR）第二阶段项目将开发计算流体动力学（CFD）建模技术，该技术使用最先进的技术来模拟化学反应湍流中的有限速率化学反应，并使用最近开发的数值方法来求解非线性方程组。 在第一阶段，开发了一种改进的CFD求解器，该求解器使用简化的化学动力学机制来模拟有限速率化学效应，并使用无矩阵牛顿-克雷洛夫方法求解所得的偏微分方程刚性系统。 在第二阶段，将开发两个基于Newton-Krylov的CFD工具，一个用于模拟湍流扩散火焰的燃烧，第二个用于模拟湍流预混合火焰。这项工作的商业潜力是电力工业，商业化工厂的设计者和建造者，以及化学工艺加热器和其他工业炉应用的设计者。
