采用K—ε湍流模型、SIMPLER方法对JS-2燃煤磁流体燃烧室的冷态流场进行了数值计算,并做了一系列冷模试验研究。通过对几种不同结构燃烧室的计算与测量所得出的流场的分析比较,提出了一些改进JS-2燃煤磁流体燃烧室的建议,最后对计算与测量方法进行了讨论。
The K-ε turbulence model and the SIMPLER method were used to calculate the cold flow field in the JS-2 coal-fired magneto-fluid combustor. A series of cold model tests were also conducted. Based on the analysis and comparison of the flow field calculated and measured by several different combustion chambers, some suggestions for improving the combustion chamber of JS-2 coal-fired magnetic fluid are proposed. Finally, the calculation and measurement methods are discussed.
