Numerical anaysis methods are developed for estimating the effects of bubble circulation as counter measure in Reservoirs. Two demensional reservoir model (JWA model) are used for the platform for analysing flow in reservoir including bubble plume currents. New knoledge of the characteristics of ambient horizontal flows induced by double plule under actual reservoir conditions are used for the revision of double plume model. By some numerical experiments, overestimation of the horizontal flows by previous and general double plume model was clarified.
