| 摘 要： | 针对所提出的用空气室引发水力共振以增强脉冲水射流的设想,应用水力瞬变特征线解法,建立系统的数学模型,差分网格只取脉冲源、空气室和喷嘴3个边界点,采用变时步法解算。这种方法具有灵活性大、受限制小、便于使用的突出优点。

| Abstract: | Applying the Method of Characteristics, the paper structures the mathematic models for analyzing the phenomena of pulsed water-jet system embodied air-chamber. The differential grid has three boundaries only,eg. pulse source, airchamber and nozzle, none interior node being involved. For dealing with the condition that the lengths of upstream and downstream sections may be unequal, the novel Variable Time Step Method is adopted. This analysis technique has the glaring advantages of flexibility, less limit, and convenient for use. |
