Visualization of Inception, Propagation, and Collapse Process of Underwater Positive Streamer
Visualization of a whole process of underwater positive primary streamers is difficult because the time scales among inception and propagation of streamers, collapse of streamer gas channels, and formation of residual fine bubbles are different and the spatial scale is a micrometer scale. This study succeeded in successive visualization of the whole process of the streamer with a frame rate of 10 Mfps.
