可压剪切层线性稳定性特征直接数值模拟

基于伪随机数生成技术促生白噪声扰动，以高精度迎风/对称紧致混合差分算法求解二维/三维非定常可压Navier-Stokes方程，揭示了可压自由剪切层初始剪切过程中扰动的线性演化特征，以及该过程对扰动波数方向的内在选择性。验证了所用算法的有效性，表明线性理论同数值模拟相结合是可压剪切层研究的合理途径之一。

A shock tube method in the kinetic study of nonequilibrium ionization-recombination by rarefaction wave cooling

A shock tube method is introduced to study the ionization–recombination kinetics of high temperature gas, in which a test gas is heated and ionized by a reflected shock wave and subsequently quenched by a strong rarefaction wave reflected on the end wall of the driver section as the main cooling wave associated with a rarefaction wave incident back into region 5 when the reflected shock wave interacts with the contact surface. As the quenching rate of the strong rarefaction wave reaches 106 K/s, a nonequilibrium ionization-recombination process occurs, during which the ion recombination with electrons dominates.
