一种新型二元风洞侧壁干扰修正方法——当地修正法

A New Method to Correct Sidewall Interference in Two Dimensional Wind Tunnels ——A Local Correction Approach

针对现行总体型二元风洞侧壁干扰修正方法的不合理性，本文发展了一种新型修正方法——当地修正法，并就有关问题做了讨论。与目前的总体型方法相比，当地修正法致力于对模型当地流动参数的修正，而不是笼统地去调整试验条件。当地修正法有能力处理那些主要的侧壁边界层效应及相关问题，是未来开展侧壁干扰修正的一条有效途径。

In view of the invalidity exposed in available global type corrections for sidewall interference in 2 D wind tunnels,a new correction approach——a local type one was developed in this study.Meanwhile,some problems associated with the sidewall interference were discussed.Compared with those global type rules,the new method focuses correction emphasis on local flow parameters over the model rather than testing conditions.It is able to cope with those primary sidewall boundary layer effects and relevant problems,and is an effective approach to realizing the correction for sidewall interference in future.
