Abstract: By research on underwater speed characteristics of bubbles with different diameter, the bubble diameter which produces efficient water disturbance is obtained. With the disturbance of bubbles, flow field is formed which would stop the generation of ice core. Proved by engineering application, this is an advanced and effective anti-icing method.
