摘要
A laser image measurement has been employed to quantify the volume and shape of twin-bubble generated in semitransparent glycerol aqueous solutions with high viscosity. The bubble generation regime was investigated by analyzing the shape evolution process of captured bubble, and the influences of solution mass concentration, orifice diameter and orifice interval on bubble's detached volume were discussed, respectively. The results show that twin bubbles formation experiences three stages of radial expansion, axial elongation and vertical detachment. Bubble detachment volume increases with the solutions concentration but decreases with orifice diameter. The detached volume climbs with the orifice interval, however smaller than that formed at single orifice.
