摘要

Abstract

The results are given of measuring the distributions of velocity and density in high-speed ( \(1.7{-} 4\) km/s) shock-induced particle flows ejected from the free surface of tin and copper liners into a vacuum (less \({{10}^{3}}\) Pa) or nitrogen ( \({{10}^{5}}\) and \(8 \times {{10}^{5}}\) Pa). On the surface of the liners, periodically repeating triangular grooves with a depth of 50 and a width of 250 μm were applied ( \(2{{a}_{0}}{\text{/}}\lambda = {\text{50/250}}\) μm). The experiments used multiframe registration using synchrotron radiation and laser heterodyne interferometry. Pressure of \( \approx {\kern 1pt} 45\) GPa in the shock waves reaching the free surfaces of the liners caused the tin to melt, while the copper remained in a solid state. There is a significant difference in the structure of the flows ejected from the surface of copper and tin liners, and the speed of their deceleration in gas.
