It is known that a precursor is formed ahead of the wave front when a shock wave interacts with a hot thin surface layer. In this case for weak and moderate shock waves the maximum pressure at the measurement points on the surface is less than for sh

Publikováno v: Shock Waves. 4:35-40

A method of possible diagnostics of supersonic flows around a blunt body and its aerodynamic characteristics by means of a thin channel of reduced density emerging in front of the bow shock wave is discussed. The channel was placed parallel to the bo

Propagation of a shock wave in a locally anisotropic medium containing channels with elevated thermal diffusivity

Autor: I. V. Nemchinov, V. I. Bergel'son, D. V. Pomazkin

Publikováno v: Journal of Engineering Physics and Thermophysics. 66:571-577

We consider the interaction between a shock wave and thin extended channels with elevated a thermal diffusivity. It is shown that a thermal perturbation ahead of the shock wave front leads to the effect of a “warm layer,” i.e., to the formation o

Plane shock wave cumulation in a tube with a thin wall low-density gas layer

Autor: V. M. Khazins, T. I. Orlova, V. I. Bergel'Son, I. V. Nemchinov

Publikováno v: Journal of Engineering Physics and Thermophysics. 65:867-870

A new effect of focusing of a shock wave disturbed by a thin low-density gas layer localized near the side wall of the cylindrical tube, followed by the wave reflected from the flat tube end, is analyzed numerically.

Vortex flows induced by interaction of a shock wave with thin regions of finite length and reduced density

Autor: I. V. Nemchinov, T. I. Orlova, V. A. Rybakov, V. I. Artem'ev, V. I. Bergel'Son, S. A. Medvedyuk, V. M. Khazins

Publikováno v: Fluid Dynamics. 28:411-414

A theoretical and experimental investigation has been made of the dynamics of the vortex flow induced by thin regions of reduced density in precursors that develop ahead of shock fronts during the propagation of shock waves through a channel and afte

Interaction of a plane shock wave in water with a thin layer of lower density

Autor: I. V. Nemchinov, V. I. Bergel'Son, T. I. Orlova, V. M. Khazins

Publikováno v: Journal of Engineering Physics and Thermophysics. 62:157-159

A numerical analysis is conducted on the interaction of a plane shock wave in water with a thin layer of lower density, which is perpendicular to the wave front. Parameters are defined for the perturbed flow structure and for large-scale precursors,
