Works on computational bubble dynamics having carried out since 1990 in Laboratory of Multiphase Flow Engineering in Kobe University are reviewed in this report. The topics discussed are a feasibility study on interface tracking simulation, modeling of interfacial forces acting on a bubble such as drag and transverse lift forces, a 3D two-way bubble tracking method which can cover a wide range of length scales in a bubbly flow, a 3D one-way bubble tracking method for the prediction of time-spatial evolution of a developing bubbly upflow in a vertical pipe, an averaging method based on a 3D two-fluid model in general curvilinear coordinates, and an averaging method based on a 3D multi-fluid model that can account for a bubble size distribution in a given flow.
