Simulation Research on Air-Liquid Hydraulic Resonance for Enhancing Surge Pressure

Abstract:

In pipeline transportation, hydraulic resonance is a particular fluid transient phenomenon, which maybe produces high surge pressure. Especially with air cavity being trapped in liquid pipeline, so must be avoided. However, this behavior may be used to prompt flow vibration to enhance the surge pressure for some special purposes, for example, pulsed water jet, water cannon, and so on. Based on this viewpoint, an approach of making use of the air-liquid hydraulic resonance in a pipe connected with an air-chamber to generate high pressure is put forward. The mathematic model of the system is established and numerically simulated. It is shown that, under some certain conditions, hydrodynamic resonance can take place because of the air-liquid transient, so the pipe outlet jet pressure can be enhanced remarkably.
