标题： Prediction of shock structure using the bimodal distribution function

摘要： 对预测一维激波解的Mott-Smith方法进行了修改。 使用Mott-Smith分布函数来构建矩方程组，以研究麦克斯韦分子气体和氩气中激波的稳态结构。 将使用新提出的公式预测的激波解与实验数据、直接模拟蒙特卡洛（DSMC）解以及其他现有理论预测的解进行了比较，适用于马赫数M<11的情况。 在不同马赫数下计算出的密度、温度、热流密度分布和激波厚度已被证明与实验和DSMC解有良好的一致性。 此外，预测的激波厚度在低马赫数下与DSMC模拟结果一致。 显示英文摘要

摘要： A modification of Mott-Smith method for predicting the one-dimensional shock wave solution is presented. Mott-Smith distribution function is used to construct the system of moment equations to study the steady-state structure of shock wave in a gas of Maxwell molecules and in argon. The predicted shock solutions using the newly proposed formalism are compared with the experimental data, direct-simulation Monte Carlo (DSMC) solution and the solutions predicted by other existing theories for Mach numbers M<11. The density, temperature, heat flux profiles and shock thickness calculated at different Mach numbers have been shown to have good agreement with the experimental and DSMC solutions. In addition, the predicted shock thickness is in good agreement with the DSMC simulation result at low Mach numbers.
