摘要
根据质量和能量守恒定律建立凝汽器真空的动态特性数学模型,并在simulink环境下进行仿真计算,研究分析各参数对凝汽器真空的影响。提出用相关经验公式来计算总传热量并考虑漏空气量对传热的影响进行修正,既简化了模型又有很好的工程精度。
According to conservation of mass and energy, the mathematical model for the dynamic characteristics of the condenser vacuum was established and calculated under “simulink”to analyze the impact of various parameters on condenser vacuum. Total heat transfer was computed using empirical formula while the influence of air leak was taken into account. As a result, the vacuum model was simplified and good engineering precision was obtained.
