| Abstract: | 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. |
