About correctly comparing wind tunnel experiments with flyover measurements

Abstract:
The comparison of wind tunnel experiments with flyover measurements is a common problem. Actually, the applicable rules are well understood and easy to use. However, experience draws a different picture. There seems to be a widespread confusion about the correct transformation and how to get the details right. This can lead to incorrect evaluations as well as a mix-up of various phenomena such as Doppler shift, convective amplification and convective transport. While this can often be accepted as long as data remains within the responsible group, it becomes a major difficulty for extended collaboration or when publishing for more widespread use. A common understanding is crucial for the interpretation of results as well as for correct further processing of data.This contribution aims to raise the awareness of how to correctly evaluate data in order to compare wind tunnel experiments with flyover measurements. It will visually explain the necessary procedure, while also discussing the above-mentioned effects like Doppler shift and convective amplification. The goal is a better understanding of this common problem for a better collaboration between different groups and partners.
