Abstract

We combine simple experiments and numerical simulations to study the effect of a large, single gas bubble rising underneath a floating body. Our motivation is the possible hazards arising from naturally occurring methane gas hydrates in the North Sea. For floating bodies that possess a hull length of similar scale to the bubble's radius of curvature, we identify the conditions for the floating body to sink. Our experiments allow us to extend and benchmark numerical simulations using smoothed particle hydrodynamics. There is good agreement between the simulations and experiment.
