Experimental Study of Cavity Outflow and Geysering in Circular Pipes
Dynamics of air-water flows plays an important role in hydraulic engineering. Air can influence water flows in a variety of ways, such as the formation of air cavity, air entrapment and geysering in circular pipes. Cavity outflows with shock waves are not well investigated according to the existing literature. Experimental studies of geysering in transient flows are also scarce. A large physical model was established to study the cavity outflow and geysering in circular pipes. Critical non-dimensional flow rates were developed for cavity outflows according to distinct air-water interface patterns and characteristics of shock waves were determined. The effect of a vent pipe is also studied on its influence on the pressure distribution. Geyser phenomena were investigated using a 2% slope pipe connected by a horizontal one. Pressure data and recorded videos show that the pressure drop corresponds to air release in all geysering scenarios.
