摘　　要：在分析空气系统旋转盘腔作用,及对其开展流动与换热试验研究目的的基础上,利用相似理论,推导出试验研究时应遵循的进气雷诺数、旋转雷诺数、普朗特数、旋转格拉晓夫数等相似准则及准则方程,解决了试验参数选取依据及匹配等问题,并建立了初步试验方法及数据处理方法。研究成果对进行相关试验研究具有一定的参考意义,但仍需通过试验研究进行不断补充与完善。Based on the analysis of rotating cavity’s role in air system as well as research purposes of flow and heat transfer experiments, using similarity theory, the inlet Reynolds number, rotating Reynolds num-ber, Prandtl number, rotation Grashof number and criterion equation which should be followed were de-duced. Problems as basis and match for experiment parameter selection were solved, and the preliminary testing and the data processing method were established. It has the certain reference significance for the fu-ture related research. The research is referential for relative test to some degree, but it still needs incessant supplement and improvement through tests.
