Abstract

We study one-dimensional flows of an ideal (inviscid and non-heat-conducting) perfect gas with an adiabatic exponent γ behind a shock wave moving toward the center (ν = 3) or axis (ν = 2) of symmetry in a cold gas at rest. Flows with a reflected shock wave and flows terminating with simultaneous arrival of a shock wave and a piston, which has compressed the gas into a point or line, to the center of symmetry are admitted.

冲击波向对称中心或对称轴推进的自相似流

我们研究了在静止的冷气体中，具有绝热指数γ的理想（无粘性和非导热）完美气体在冲击波后的一维流动，该冲击波朝着对称中心（Γ=3）或对称轴（Γ=2）移动。具有反射冲击波的流动和以冲击波和活塞同时到达而终止的流动，活塞将气体压缩成一个点或线，进入对称中心。

期刊介绍： Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
