Abstract
The results obtained during an experiment performed in a wind tunnel must be subjected to a correction process, whose purpose is to eliminate the influence of the limited dimensions of the airflow on the flow around the model. This is absolutely necessary because it is desired to bring the results to a form that is independent of the characteristics of the laboratory in which they were obtained. One of the many inevitable difficulties that characterize the experiments conducted in a wind tunnel is the interaction between the flow and the walls of the experimental chamber. Therefore, for the highest possible accuracy of the results, it is imperative to determine the effect of the walls on the flow around the model. This problem has been intensively studied, and several techniques for correcting the influence of the walls were determined. Regarding the perforated walls wind tunnels, even though they were designed to minimize the effect of the walls, these corrections are still necessary. The aim of this paper is to present an overview of the correction methods applied in a perforated wall wind tunnel.
