Abstract

In this study, the Reynolds number effect on the aerodynamic coefficients is investigated using NACA 4415 airfoil profile section. In the literature, there are quite a few experimental results for the low Reynolds numbers. The aim of the study is to fill this gap. For this purpose, three different Reynolds numbers which are 138e3, 154e3, and 170e3, are investigated during the experiments. The aspect ratio of the used airfoil is 4.76. The measurements of the aerodynamic forces are carried out using an open-jet type wind tunnel coupled with a three-component balance. Throughout the experiments, it is observed that the lift coefficients increase with the increasing Reynolds number.
