The effect of initial bubble conditions on the motion of a gas bubble rising in viscous liquids was investigated by 3d-computations. Then, a coupled level set/volume-of-fluid (CLSVOF) method was used as a numerical method. For low Eotvos and very low Morton numbers regions predicting bubble motion with non-linear behavior, it was computationally demonstrated that the resulting final state of bubble depended on initial bubble conditions: different bubble rising motion depending on initial bubble conditions were numerically reproduced. The numerical results obtained in this study agreed with the experimental observation by Tomiyama et al.
