大型汽动设备动态性能仿真研究

A Study on Performance Simulation for Large-sized Steam-powered Equipment

根据气体动力学、热力学、二相流理论建立了大型汽动设备的主系统数学模型，并编制了计算程序，计算结果与国外相应数据比较吻合度较好，从而为该设备总体设计及分系统设计提供了强有力的理论指导和设计原则。

Based on fluid dynamics,thermodynamics and two-phase flow theory,a mathematical model is set up for a large-sized steam-powered equipment,and the performance simulation is also made. The calculation results are satisfactory as compared with experiment of the similar foreign equipment.
