A numerical model has been developed for simulation of bubble flow, with consideration of gas compressibility and oxygen dissolution. Developed model is intended to be utilized for simulation of lakes DO recovery by means of electrolysis. Model is firstly verified by simulation of bubble flow experiments, reported in the literature, where very good quantitative and qualitative agreement between measured and simulated results is observed. Both flow configurations are tested: in which steady state is achieved, and where steady conditions can not develop. Simulations of bubble plumes with oxygen dissolution revealed that, in the lake environment, significant dissolved oxygen spreading can not be expected. Therefore, some additional measures, which will enhance dissolved oxygen distribution, should be considered.
