燃气轮机燃烧室流场数值计算研究及分析

对燃气轮机逆流式环形燃烧室，热态三维流场的数值模拟问题进行了研究，建立了三维计算模型，生成了数值计算网格。数值模拟研究表明，改变燃烧室的几个结构参数，可以得到更加合理的流场。通过对关键截面的流动分析，可以判断燃烧室设计的合理性，为进一步优化燃烧室结构设计、改善流场奠定了基础。

Research and Analysis of Flow Numerical for Gas Turbine Combustor

In this thesis, numerical simulation method of heat three-dimensional turbulent reacting flow was studied about a reverse flow combustion chamber of gas turbine. Mathematical model of the combustor was developed, generate the reasonable mesh for compute. The numerical simulation for change some parameter of the combustor in order to get better flow field was indicated. It can estimate the rationality of the combustor design, which was the basis of optimize the combustor design, by the flow analysis of key section.
