| 摘 要： | 提出了一种新的求解复杂稳态全速度统一流场的方法,即先采用PISO算法计算一假想的非稳态流场用以获得一时间点上的流场参数分布,然后将这一时间点上的流场参数作为初场,用SIMPLE算法进行稳态流场的计算,进而得到较满意的收敛结果。用这种方法计算了某燃气源控制气流在假定固体壁面为绝热边界的条件下的三维热流流场,得到了流场的各参量分布情况,并与冷流的计算结果进行了比较分析。

| Abstract: | A new method to solve the complex steady flows with all speeds was presented, that is an imaginary transient flow was solved by PISO algorithm first for getting a reasonable flow field parameters distribution at one moment, which would be treated as initial flow field parameters distribution, then to solve the practical steady flow by SIMPLE algorithm to get the final satisfactory converge of results. Using this method, the three-dimensional hot gas control flow with adiabatic wall boundaries was solved. The numerical results were analyzed and compared with the results of the cold flow. |
