微小通道内液体扰流微孔逸出气泡串的迁移行为
Migration behavior of bubble cluster emerging from micro-orifice with liquid cross flow in mini-channel
摘要
Abstract
Visualization experiments were performed on migration behavior of bubble cluster emerging from a micro-orifice with liquid cross flow in a mini rectangular channel. Based on the self-developed image processing method, the influences of liquid flow rate and inclination angle of the channel on the size, velocity and trajectory of bubble cluster were discussed. Meanwhile, micro-bubbles accumulation at the top wall of the channel was observed and analyzed under different operating conditions. The bubbles size as well as the angle between bubble trajectory and channel bottom wall decreased with increasing liquid flow rate and inclination angle of the channel. Furthermore, the location and number of the micro-bubbles accumulated at the top wall were distinctly affected by liquid flow rate and channel inclination angle.关键词
