• For energy conservation reasons, viscous drag reduction is of great interest for full scale ships. A lot of references report skin friction or total drag reduction when bubbles are injected into the boundary layer on the hull. As experiments on a full scale ship is almost impossible, the scale effect in the trajectory of bubbles injected at the bottom of a hull was investigated using geosim models. After a description of the experimental work, the numerical scheme used to compute the bubble trajectories is explained. Then the experimental and numerical results are presented and discussed. The influence of the scale effect and of the injection location is shown.
