一维Riemann问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度MacCormack两步差分格式进行数值求解。同时，为了初学者入门和练习方便,这里给出了用Fortran77语言编写的计算一维Riemann问题的计算程序，供大家学习参考。——计算流体力学教程-One-dimensional Riemann problem, that shock tube problem is a typical one-dimensional compressible inviscid gas dynamics, and analytical solution. Its second order accuracy MacCormack two-step numerical solution of difference scheme. Meanwhile, for beginner and practice convenience, here are written using Fortran77 one-dimensional Riemann problem of the calculation of the calculation procedures for them to learn information.- Computational Fluid Dynamics Course
