초록
Vortexing might occur during draining from tanks which reduces the rate of outflow. This phenomenon has practical relevance in the fuel feed system in space vehicles and rockets. Due to environmental disturbances rotational motion can be generated in the liquid-propellant tank, which in turn can affect the rate of outflow to the engines. The phenomenon is initialized by rotating the fluid In the experimental tank. The dip quickly develops into a vortex with an air core, which extends to the bottom port, reducing the effective cross-sectional area of the drain outlet and consequently the flow rate. Flow characteristics are investigated using SPIV(Stereoscopic Particle Image Velocimetry) method.
