But the influence trend of the maximum rolling angle and the rolling period was not so simple , it was because the influence of which embodied in the phase relationship of mass flow and the pressure drop across the tube . the d - partition method was developed to separate the test tube into four regions and the drift flow model was imported into the two phase region , based on which the solution of the response of the pressure drop of tested tube to the inlet mass flow perturbation can be obtained 在不摇摆和摇摆工况下,采用d分区法对实验段进行分区,在两相区采用漂移流模型对实验段的压降对入口流速扰动的响应进行了求解,给出了各区压降响应的表达式,进而得到了在不摇摆和摇摆工况下,压降与入口流速扰动之间的传递函数。
