【摘要】 本文以核电站为背景,讨论了蒸汽在直管道中的汽锤计算。把水蒸汽当作可压缩的非完全气体来处理,用特征线法计算汽锤,解决了非完全气体模型带来的困难,节省了计算时间。最后用矩形网格法的计算结果与实际作了比较,两者吻合较好。更多还原

【Abstract】 The steam hammer is set up by the turbine stop valves slamming shut after a turbine trip in power plant. In this paper, characteristic methods are used to calculate the steam which is considered as a non-perfect gas, and flow is assumed to be isentopic flow, it overcomes the difficulties caused by the model of the non-perfect gas, and saves the culculation time. The two results both from the experiment and from calculation coincide quite well.更多还原
