Abstract:

The dataset includes simulation data of bubble size distribution from a typical subsea gas blowout predicted by VDROP-J model. The size of a gas bubble changes due to gas dissolution in the ambient water and expansion as a result of a decrease in water pressure during the rise. In this work, we used the numerical droplet formation model VDROP-J to simulate gas formation in jet/plume upon release, with a development of gas expansion and dissolution module using the differential form of the real gas law. These data have been used to generate figures in Zhao. L, M.C. Boufadel, K. Lee, T. King, N. Loney, and X. Geng (2016), Evolution of Bubble Size Distribution from Gas Blowout in Shallow Water, Journal of Geophysical Research - Oceans, 121, 1573-1599.
