摘要

为探究第三钝体对双凹腔先进旋涡燃烧室内部冷态流动特性的影响,通过数值模拟其冷态流场,研究了不同钝体结构参数对燃烧室总压损失及旋涡结构的影响;在已有的最佳两钝体结构基础上增加第三钝体,采用改变来流条件的方法,研究了流速度对旋涡燃烧室流动特性的影响。结果表明,第三钝体的几何尺寸及来流速度变化对燃烧室内部的流场影响显著。

Abstract

To explore the influence of the third blunt body on flow field of advanced vortex combustor, influence of blunt body structure on total pressure loss and vortex has been studied, the numerical simulation under cold and combustion conditions has been carried out. Then, analysis on the influence of different flow speed on combustor flow field was made. The results show that both geometrical dimension change of the new added blunt body and the flow velocity change may significantly influence internal flow characteristics of combustor.

Key words： advanced vortex combustor; double cavities; combustion; numerical simulation
