摘要
建立了旋转条件下细微封闭循环通道中流体热驱动流动规律和换热特性的基本控制方程,并进行无量纲化,得到了影响流体热驱动换热的主要准则参数;在理论分析的基础上通过实验研究离心力场下以H2O为热驱动介质时各准则参数对换热的影响,拟合获得了离心力场下热驱动换热特性相似准则关系式。
Basic governing equations were established to investigate flow and heat transfer characteristics of the thermally driven liquid flow in the enclosure circulation channels in centrifugal force field. From the dimensionless governing equations, the primary similarity criteria, which affect the thermally driven heat transfer were gained. Experiments based on theoretical analysis were carried out to investigate the details of heat transfer of water in centrifugal force field. Through curve fitting of the test data, the similarity criteria for thermally driven heat transfer in centrifugal force field were obtained.
