摘要/Abstract

摘要： 给出了一个单相受热管模型,以某电站锅炉过热器受热管为对象,通过仿真研究了忽略动量方程瞬态项对模型性能的影响。研究发现,忽略动量方程瞬态项会显著降低单相受热管模型的动态精度,在各种阶跃扰动下忽略动量方程瞬态项都会使模型焓-温通道的动态响应速度加快近4倍,在入口蒸汽流量阶跃扰动下忽略动量方程瞬态项会改变模型压力-流量通道的动态特性类型;忽略动量方程瞬态项所换来的计算耗时下降不足7%;并且忽略瞬态项后模型保持数值稳定的能力也有所降低。

关键词: 单相受热管, 过热器, 仿真模型, 动量方程, 瞬态项

Abstract: A model of single phase heated tubes was presented, based on which the effect of neglecting transient terms of momentum equations on model performance was investigated by simulating a heated tube of the superheater of a power plant boiler. It is found that neglecting the transient terms of momentum equations can significantly decrease the dynamic accuracy of the model; under various step disturbances, neglecting the transient terms of momentum equations can speed up the dynamic response of the enthalpy-temperature channel of the model nearly 4 times; under the step disturbance of the inlet steam flux, neglecting the transient terms of momentum equations can change the type of dynamic characteristics of the pressure-flow channel of the model; whereas the corresponding decrease of computational consuming time is less than 7%; moreover, the ability to keep numerically stable also decreases.

Key words: single phase heated tube, superheater, simulation model, momentum equation, transient term
