DOI: 10.1017/jfm.2019.839
Abstract: Gust/turbulence–leading edge interaction is a significant source of airfoil broadband noise. An approach often used to predict the sound is based on Amiet’s flat-plate solution. Analytical studies have been conducted to investigate the influences of… read more here.

DOI: 10.2514/1.j056853
Abstract: Acoustic vectors, such as acoustic velocity and acoustic intensity, have advantages over acoustic scalars in showing the detailed propagation path of acoustic energy. In this paper, acoustic vector... read more here.
