Abstract:

The formalism of transport theory is adapted to a general description of bubble populations in a moving fluid. The bubble distribution, as a function of position, velocity, radius, and time, satisfies a Boltzmann type transport equation that is derived and then formally solved by the method of characteristics. Properties of the medium are specified and a bubble dynamics model is chosen. General expressions are written for bubble acceleration and radius change rate, and known models of bubble gas diffusion and drag are summarized for gas bubbles in liquids. Application to the upper ocean is discussed and illustrated with some sample calculations.
