The theoretical study was carried out to clarify the mechanism of bubble formation through a submerged nozzle in upward water flow. On the basis of the experimental results, a model of breakup of the air column in which the surface membrane is oscillating at the top of the nozzle due to the disturbance of flow was proposed. The size of the bubble generated from a nozzle in a stream ranging from Nozzle Reynolds number 1500 to 15000 was determined by applying the theory of the instability of a jet which was first analyzed by Lord Rayleigh. The proposed model is in good agreement with the experimental results.
