On the mass of the liquid attached to a moving bubble separated from the electrode surface by a spark discharge

The mechanism of detachment and motion of gas bubbles from the GaAs surface, initiated by a spark discharge in an aqueous electrolyte, is investigated. The model proposed for the displacement of bubbles in the liquid is based on the theory of the formation of a water ram pressed by a gaseous inclusion out of the compacted layer of the liquid as a result of action of the compression wave produced by a spark discharge. The effect of the size and temperature of a gas bubble on the geometrical parameters of the water ram is considered. The lifetime of the water ram is determined from the pressure drop at the leading edge of the compression wave.
