SBIR Phase II: Multi-Environment Probability Density Function (PDF) Method for Modeling Turbulent Combustion Using Detailed Chemistry

小型企业创新研究(SBIR)第二阶段项目将扩展多环境概率密度函数(MEPDF)方法的适用性，以在实际燃烧设备的全面计算流体力学(CFD)模拟中模拟具有真实化学动力学的湍流燃烧问题。该项目旨在进一步推进MEPDF方法，将其扩展到模拟工业上相关的单相和两相燃烧系统，例如使用稀薄预混气体燃烧器燃烧的化学过程炉；燃油公用事业锅炉和工业炉；以及煤气化设备。关于将MEPDF方法扩展到使用复杂化学动力学模拟实际燃烧系统的拟议活动将产生一个工具，它将加强这些过程的科学和工程知识库。该项目产生的先进模拟工具将为发电、化工、矿产加工和焚烧行业的公司提供一种改进产品设计和服务的手段，这反过来将有利于环境、全球竞争力和国家/国土安全。

This Small Business Innovation Research (SBIR) Phase II project will extend the applicability of the multi-environment probability density function (MEPDF) method to model turbulent combustion problems with realistic chemical kinetics within comprehensive Computational Fluid Dynamic (CFD) simulations of practical combustion equipment. The project aims to further advance the MEPDF method by extending it to simulate industrially relevant single-phase and two-phase combustion systems, such as chemical process furnaces fired with lean pre-mixed gas burners; oil fired utility boilers and industrial furnaces; and coal gasification equipment. The proposed activities for extending the MEPDF method to simulate practical combustion systems using complex chemical kinetics would result in a tool that will enhance the scientific and engineering knowledge base for these processes. The advanced simulation tools produced from this project would provide a means for companies in the power generation, chemical process, mineral process, and incineration industries to improve product designs and services, which in-turn would benefit the environment, global competitiveness and national/homeland security.
