Whether the compressor surge for start / stop to avoid, so for turbine blade cooling gas at all levels in the operation of the supply, is through the process of compressor exhaust system to complete the. Reasonable and useful air pumping system is to ensure all the unit is safe, stable operation and start and stop will have to put into a little guarantee. The whole pumping gas compressor system includes external pumping structure and internal suction piping two department. The reasonable design of the external gas pumping structure can reduce the loss of pumping gas. Suction surface pumping is one of the most useful methods for gas turbine compressor. This paper mainly studies with air cavity static blade suction surface effects on the parameters and flow field, and the gas turbine exhaust piping modeling, open piping design system. In the discussion of external pumping construction, important assessment single gas cavity pumping, high leaf blade height department and double cavity pumping pumping three department leaves high pumping method. On the whole leaf high pumping and pumping test department leaves high effect gas cavity size, the size of the exhaust volume of these two factors on the function of double cavity pumping also examine influence pumping groove outlet width differences. Study notes, useful extraction more Nianye tip and Ye Genchu were restrained the consequences better, but also cannot too big, otherwise will be pumped into the mainstream at the same time, the new year night pumping quantity also easily forming a suction groove kind cavity infarction, make effect with pumping volume growth, in some cases even the effect decreased with the increase of pumping quantity. The study also notes, single gas cavity pumping structure is simple, but the exhaust volume of a suction groove divided into control and Bufu, double cavity pumping is the suction slot flow dispersion controllable, but more complex structure. Design of the compressor external pumping structure, to consider the following factors mentioned above. Suction piping in the internal study, this paper analyzes the color bleeding pipe network node crossroads relatively frequently used method, set up the mathematical model of one-dimensional heat transfer with single-phase fluid tight, and adopt implicit numerical method of calculating the progress of the computing speed, so that we can quickly obtain perhaps activity parameters of gas piping system smoke complex, such as the flow of each node and each branch pipe of the pressure and temperature. This paper will design and design work on inorganic internal pumping pipe external pumping structure together, build the compressor pumping system preliminary design platform.目录:摘要3-4ABSTRACT4-5第1章 引言10-18&&&&1.1 研究背景10-11&&&&1.2 研究目的11-14&&&&1.3 研究现状14-17&&&&1.4 本文的主要工作17-18第2章 数值计算方法和研究对象18-25&&&&2.1 数值计算方法18-23&&&&&&&&2.1.1 N-S 方程介绍19-20&&&&&&&&2.1.2 S-A 模型介绍20-21&&&&&&&&2.1.3 研究工具21-23&&&&2.2 研究对象23-25第3章 带气腔抽气的分析25-61&&&&3.1 算例汇总25&&&&3.2 带气腔抽气与无气腔抽气比较25-28&&&&3.3 单气腔全叶高抽气28-38&&&&&&&&3.3.1 计算设置28-30&&&&&&&&3.3.2 结果分析30-38&&&&3.4 单气腔部分叶高抽气38-48&&&&&&&&3.4.1 计算设置39&&&&&&&&3.4.2 结果分析39-48&&&&3.5 双气腔部分叶高抽气48-59&&&&&&&&3.5.1 计算设置49-51&&&&&&&&3.5.2 结果分析51-59&&&&3.6 本章小结59-61第4章 抽气配管网络数学建模61-86&&&&4.1 拓扑结构分析61-63&&&&4.2 流体网络基本方程63-67&&&&&&&&4.2.1 质量守恒方程63-64&&&&&&&&4.2.2 动量守恒方程64-66&&&&&&&&4.2.3 能量方程66-67&&&&4.3 控制方程的离散67-73&&&&&&&&4.3.1 离散后的代数方程67-68&&&&&&&&4.3.2 压力矩阵和焓矩阵68-73&&&&4.4 能量方程中换热项的计算73-78&&&&&&&&4.4.1 支路管道传热系数的计算73&&&&&&&&4.4.2 管内强制对流换热-湍流73-74&&&&&&&&4.4.3 管内强制对流换热-层流74-75&&&&&&&&4.4.4 管壁的导热75-76&&&&&&&&4.4.5 管外自然对流换热76-78&&&&4.5 管件的损失模型78-84&&&&&&&&4.5.1 沿程阻力损失78-81&&&&&&&&4.5.2 局部阻力损失81-84&&&&4.6 本章小结84-86第5章 稀疏线性方程组的求解86-91&&&&5.1 概述86-87&&&&5.2 列主元高斯消去法87-88&&&&5.3 逐次超松弛迭代法88-90&&&&5.4 本章小结90-91第6章 系统设计及算例分析91-104&&&&6.1 系统设计91-95&&&&6.2 算例分析95-103&&&&&&&&6.2.1 T 形管网95-98&&&&&&&&6.2.2 某型燃气轮机的抽气配管管网的计算98-103&&&&6.3 本章小结103-104第7章 结论和展望104-106&&&&7.1 本文的总结104-105&&&&7.2 展望105-106参考文献106-109致谢109-110个人简历、在学期间发表的学术论文与研究成果110分享到:相关文献|> 问题详情
