摘要
构建了倾斜变截面管理想流体喷射模型并采用数值模拟的方法来研究不同倾角下温度、管径比、初始水量等参量的改变对最大喷射高度的影响.结果表明,升高温度、减小倾角、增大管径比、降低初始水柱高度等均可增加最大喷射高度.最后则研究了垂直状态下变截面管的管径比对最大喷射高度的影响,发现随着管径比的增大,最大喷射高度会趋于稳定.
The method of numerical simulation was used to study the effect of the changes of parameters,such as temperature,diameter ratio and the initial water flow rate on the maximum jet height at different inclination angles.The results showed that increasing the temperature,decreasing the inclination angle,increasing the diameter ratio,decreasing the initial water column height and other methods could increase the maximum jet height.Finally,the influence of the diameter ratio of vertical variable cross-section pipe on the maximum jet height was analyzed and found that the maximum jet height would stabilize with the increase of the diameter ratio.
