摘要
该文以石油、化工和火电厂常用的换热器为研究对象 ,对其仿真动态数学模型的算法进行了研究 ,重点讨论了梯形法、改进的欧拉法、四阶龙格—库塔法和动态因子法的数值解的稳定性、计算速度以及精度 。
The heat-exchanger is taken as the object of the research, which is widely used in the petrolic and chemical industry and the thermal power plant. The computational methods of the simulation of its dynamic mathematical model are mainly researched, and the numerical stability, computational velocity and precision of four methods that are improved Euler method, fourth order Runge-Kutta method, trapezoidal method and dynamic factor method are discussed, and the best method is chosen from them.
