AB  - The paper presents a novel method for hypolimnetic oxygenation by electrolysis of water. The performance of the method is investigated by the laboratory and the field experiment. The laboratory experiment is conducted in a 90 L vessel, while the field experiment is conducted at the lake Biwa in Japan. In order to provide a better insight into involved processes, a numerical model for simulation of bubble flow is developed with consideration of gas compressibility and oxygen dissolution. The model simultaneously solves 3-D volume averaged two-fluid governing equations. Developed model is firstly verified by simulation of bubble flow experiments, reported in the literature, where good qualitative agreement between measured and simulated results is observed In the second part, the model is applied for simulation of conducted water electrolysis experiments. The model reproduced the observed oxygen concentration dynamics reasonably well.

AB  - One of available lake restoration technologies is injection of compressed air or oxygen into a hypolimnion, promoting vertical mixing of water and dissolution of oxygen.A numerical model has been developed for simulation of bubble flow, with consideration of gas compressibility and oxygen dissolution. The developed model is intended to be utilized for simulation of lakes DO recovery. The 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 flowconfigurations are tested: inwhich steady state is achieved, andwhere steady conditions can not develop. In the second part, model is applied for simulation of conducted experiments where oxygen dissolution has been considered. The paper presents simulation results, where good agreement of simulated and measured quantities is observed.
