A review of trailing edge noise generated by airfoils at low to moderate reynolds number

Abstract

This paper contains a detailed literature review of research findings regarding the cause of flow-induced noise created by airfoils operating at low to moderate Reynolds numbers. There are many important engineering applications that operate at these conditions. More investigation is required to understand why airfoils in this range of Reynolds numbers produce high levels of tonal noise. As discussed in this paper, there are still many uncertainties surrounding the nature of the source.
