摘要
针对柱对称二维流体力学方程组,基于考虑方程右端附加源项的人为构造解方法,构造出一类统一形式的人为解.此类形式的人为解,对验证多维流体力学应用程序的正确性有重要的作用.同时将该类统一形式的人为解应用到PPM格式的程序,验证了构造的人为解的可行性.
In this paper, we constructed manufactured solutions of 2D hydrodynamic Euler equations based on the artificially additional source terms. The manufactured solutions are important to code verification in CFD simulation. We applied this manufactured solutions to the code with PPM scheme. That verified the manufactured solutions in this paper be feasibility to code verification.
