A three-dimensional one-way Bubble Tracking Method has been proved to give good predictions for the spatial evolution of flow pattern, mean void fraction, void fluctuation, mean pressure drop and pressure drop fluctuation in developing bubble flows in vertical pipes. In this study, the spatial evolution of radial developing bubble flow. As a result, it is confirmed that the method gives good predictions of local void fractions, provided that bubble size distributions at an inlet were available.
