Setting up Experiments for Analyzing Disturbances of the Head Shock Wave Due to the Presence of Particles in the Supersonic Flow

The research in the field of devices and methods of experimental physics includes, in particular, the creation of installations for conducting experiments in the physics of multiphase nonequilibrium flows. Multiphase flow around bodies is of significant importance in various fields of technology, for example, in power engineering, contact visualization methods, aerosol technologies, in the application of various coatings, etc. In the high-speed two-phase flow around bodies, the physics of particle collisions with the surface and the interaction of flying particles with the head shock wave play an important role. Most of the experiments in this area, including the passage of the model through the zone of rain, snow, dust, cooled clouds, etc., are carried out in the reverse setting. In this case, the model is fixed, and the flow is made by one or another high-enthalpy aerodynamic installation. This approach does not correspond to the initial stage of the interaction formed before the entrance to the zone of the two-phase medium, between the head shock and the incident particle. Nevertheless, for some approaches, it is of interest to visually confirm the possibility of an oncoming particle being ejected at a supersonic speed by the front of the head shock wave and to see the deceleration of the model from the shadow pattern with a change in the Mach line. The paper considers a direct ballistic experiment which by shadow visualization tests the possibility of cavern formation near a body crossing the trajectory of the atmosphere saturated with dust particles
