| 摘 要： | 针对同向两股气流掺混的某一特定物理模型,对自耦合射流作用下的气流掺混过程进行了数值模拟研究.与未施加自耦合射流激励的掺混过程相比,自耦合射流周期性的吹/吸诱导流场内产生复杂的大尺度涡系结构,使得同向两股气流形成对流型混合,有效缩减了主流核心区长度;相对于在燃烧室单侧放置激励器的方式,双侧自耦合射流激励时温度均匀分布线较...

| Abstract: | Numerical investigations on the two parallel flows mixing process excited by the synthetic jets were performed.Compared to the mixing flow field without the synthetic jet excitation,the synthetic jets induce complicated vortex structure in the mixing flow field through the periodical blow-entrain action.These vortexes force the convective mixing between two parallel flows,which is helpful to shorten the primary flow core length.The lines of low temperature are closer to the inlet with two synthetic jets on ... |
