摘要: 二元翼型试验时模型安装于侧壁转盘上会引起侧壁边界层三元效应,中国航空研究院西北工业大学和德国宇航院哥廷根流体力学研究所合作用计算和试验方法进行了研究。作者介绍了1995~1998年的研究,包含研究目的,方案,计算方法,在德国路德维希管风洞中的验证试验,结果分析和初步结论。Abstract: In two dimensional airfoil tests for models mounted on the side wall turn table may introduce three dimensional side wall boundary layer effects.CAE and DLR had done a cooperative research on this topic by calculating and measuring method to research the condition of three dimensional boundary layer effects on side wall.This paper describes the work that had been carried out since 1995~1998,including the research object and strategy,calculating method,tests in KRG for verifying and the analysis of the results as well as the primary conclusion.
