Abstract

The experimental results obtained in a wind tunnel must be subjected to a correction process which aims to eliminate the influence of the limited dimensions of the flow field around the model. This is necessary because the results must be independent of the characteristics of the laboratory where they were obtained, in order to ensure the quality of the parameters.The wall corrections are applied to the global quantities that characterize the undisturbed flow, such as the Mach number or the dynamic pressure, but they are also applied to the quantities related to the model, namely the global aerodynamic coefficients.Consequently the corrections will be applied to the global quantities of the undisturbed flow and therefore they will be transmitted to the aerodynamic quantities related to the model.

利用均质和测量边界条件评估风洞壁干扰

在风洞中得到的实验结果必须经过修正过程，以消除模型周围流场有限尺寸的影响。这是必要的，因为结果必须独立于获得它们的实验室的特性，以确保参数的质量。壁面修正应用于表征无扰动流动的全局量，如马赫数或动压力，但它们也应用于与模型相关的量，即全局气动系数。因此，修正将应用于未扰动流动的全局量，因此它们将传递给与模型相关的气动量。
