摘要
为了保证天然气管道仿真结果的可靠性、准确性,文章尝试采用巴特切(Butcher)五阶龙格-库塔法进行管道的稳态仿真。文章给出了巴特切算法用于天然气管道仿真的数值表达式和具体的仿真步骤。两个算例说明用巴特切算法实现了管道的稳态仿真,并与传统四阶龙格-库塔法的仿真结果进行比较,其特点是:当管道长度一定时,管径越大,两种方法的仿真结果越接近。建议在今后天然气管道仿真中,两种方法同时使用,相互验证。
In order to guarantee the reliability and accuracy of gas pipeline's simulation result,the article attempts to use Butcher fifth order Ronge-Kutta method to carry on pipeline's steady-state simulation.The article gives the Butcher algorithm's numerical expression and concreting simulation steps for gas pipeline's simulation.The two examples show that the Butcher algorithm has realized pipeline's steady-state simulation.In comparison with the traditional fourth order Ronge-Kutta method's simulation result,its characteristic is: When the pipeline length is certain,and diameter is bigger,two methods' simulation results are closer.We suggest using the two methods together and confirming mutually for gas pipeline's simulation in the future.
