| 摘 要： | 构建了气液两相流动的半经验波动模型，用特征线法对绝热管中初始空泡分布为阶跃脉冲的气液两相流动过程进行数值计算，研究脉冲空泡分布的流动稳定性。计算表明，脉冲空泡场具有色散波特征，存在不稳定的行波解。阶跃稳定域由阶跃初始值、终了值以及漂移通量特性决定。 |
| 关 键 词： | 数值计算 特征线法 绝热管 阶跃脉冲 行波解 气液两相流动 |

| Abstract: | The hyperbolic wave model with empiric equation of gas liquid two-phase flow is constructed. An initial-boundary value problem is considered by using characteristic-curve method.The propagation of a step change voidage distribution is numerically simulated and the instability of the propagation is discussed. Numerical simulation shows that the propagation of the voidage distribution is determined by the initial value and endpoint value of a step change as well as the characteristics of the drift-flux between liquid and gas flow. The dynamic propagation view for the transient behavior of the gas liquid two-phase flow is suggestd. |
| Keywords: | gas liquid two-phase flow characteristiccurve method propagation of a step change voidage distribution |
