Numerical simulations of movement and deformation of a single bubble in a liquid metal flow field with reciprocating stirring were conducted using the volume of fluid(VOF) method.The influences of reciprocating frequency,initial bubble diameter,surface tension,Eotvos number(Eo) and Morton number(Mo) on the behavior of bubble movement and deformation in the flow field were discussed.The results show that bubble movement trajectory is related to the bubble diameter,the reciprocating frequency of the injector and Mo.The oscillation in the bubble trajectory becomes more intensive with increasing of the bubble diameter and decreasing of the reciprocating frequency and Mo.Eo is the dominative factor determining the deformation and breakup of the bubble.The tendency of bubble breakup increases with the increasing of Eo.
