摘要
为了利用相似原理研究管内工质交变流动传热特性,从可压缩粘性流体的一般控制方程出发,推导了描述理想气体管内交变流动传热的相似准则体系,包括Va、Remax、γ、Ma、Pr和Ar,并具体分析了各准则的物理意义,以及与其它常用相似准则的关系。
In order to study the heat transfer characteristics of oscillating flow in-tube from the viewpoint of similarity theory, a similarity criterion system, consisting of Va, Re γ, Ma, Pr and Ar were deduced based on general governing equations of compressible viscous fluid. The physical meaning of each similarity criterion was analyzed and the relationships with other commonly used similarity criterions were also discussed.
