Abstract
The paper describes the results of an experimental study of a supersonic transverse flow around a cylindrical body. The complicated flow structure being formed is visualized by means of shadowgraphy and by seeding the flow with particles. The experiments are performed to study the classical transverse flow around the cylinder and the flow with ejection of a gas jet from the cylinder surface. Several locations of the hole over a circumference in the cylinder midsection are considered (the aspect ratio of the cylinder is λ = 3.2). The influence of the hole location on the flow structure formed due to supersonic interaction of the incident flow and the jet is described. The study yields new experimental data on the flow structure formed due to supersonic interaction of the incident flow and the jet for different locations of the hole. The flow patterns are provided and analyzed.
