Title

Numerical Studies Of High-Speed Cavity Flows Using Les, Ddes And Iddes

Abstract

Cavity flows arise in many aerospace applications, such as wheel wells, weapons bays, and other fuselage openings for telescopes and sensors. There are two key processes of feedback-loop mechanism which are not fully understood. First, the direct relation between feedback acoustic waves and shedding vortex at leading lip had not been clearly visualized both in experimental and numerical studies. Second, the generation mechanism of feedback acoustic waves is not clear yet, especially for high-speed cavity flows involving shock waves, Mach waves and high-speed convective shear-layer. In the present work we employ computational fluid dynamics to gain an understanding of these phenomena. © 2013 by Marcel Ilie.
