Air-water flows occur in highly turbulent flows, resulting in considerable flow bulking and energy dissipation modification. An understanding of such flows remains constrained by instrumentation limitations, scale effects and restricted analytical developments. Whereas past attempts have addressed air-water flows from a deterministic point of view, this study expands recent studies by developing a three-dimensional stochastic model for bubble kinematics prediction. This model is based on mean and turbulent velocity properties of turbulent boundary layers, thus being of interest for the study of high-velocity spillway flows. Code verification is presented accompanied by a discussion of limitations and future research opportunities.
