Abstract
The paper presents results of experimental investigation on the stability of the supersonic boundary layer in relation to natural disturbances of the first vorticity mode. The surface of the flat plate model was equipped with grooves (slots, rectangular elongated cavities) of small depth and various angles of their orientation 0 and 60°. Wind tunnel experiments have been performed at Mach number 2. It was found that with decrease of orientation angle from 60° to 0 the maximum spatial amplification rate of disturbances is also decreased. For zero angle this growth rate becomes smaller in comparison with a smooth plate. The obtained results show that the first mode disturbances in supersonic boundary layer can be stabilized by streamwise grooves of a small depth. However, presence of surface grooves of the same depth with orientation angle 60° leads to noticeable flow destabilization.
Supporting agencies: The research was carried out within the state assignment of Ministry of Science and Higher Education of the Russian Federation. The study was conducted at the Equipment Sharing Center “Mechanics” of ITAM SB RAS.
