摘要
PIV基准流场是规范PIV流场测试技术和校验流场测试数据的统一标准。文章通过分析PIV流场测试技术的发展及其基准流场技术的发展状况,对PIV基准流场建设方法进行初步研究。应用CFD方法初步评估了HTA及ITTC的建议模型,给出了基准模型周围流场结果,并与HTA提供的SPIV试验测试结果进行比较分析,对PIV基准流场的方案设计和不确定度分析进行了进一步思考。分析结果为模型标准与测试标准的建设提供了基础。
The benchmark flowfield test of PIV is the general standard of the normal flowfield test technol- ogy and the validation of test data. This paper discusses the construction method of basic flowfield by ana- lyzing the measurement technology development for PIV flowfield and its basic measurement technique. The CFD method is applied to evaluate the HTA and ITI＇C models preliminarily, and the flowflied results around the banchmark model are given to compare with the SPIV test results provided by HTA. The scheme design and the uncertainty analysis of PIV benchmark test are discussed in further detail. The analysis results could provide the basis for construction of the model standard and test standard.
