Research on Uniform Distributed Parameter Model and Numerical Simulation Method of One-Dimensional Liquid-Phase Transition System

The liquid phase transition system is widely encountered in modern engineering applications. For the improvement of several primary shortcomings existed in the dynamic process simulation models of liquid phase transition system, the uniform distributed parameter model for dynamic process of one-dimensional liquid-phase transition system has been established. An analytical-numerical mixed simulation method based on an idea tracing liquid particle is put forward. Many problems of such a system can be solved effectively by utilizing this new model, which include the numerical value stability problem that is difficult to avoid in existing dynamic simulation models, the simulation module switch frequently problem, the exactly establishing of the transient position of phase transition point, etc. Thus, it has been presented an effective methodology for the modeling and simulating of one-dimensional liquid-phase transition system.
