Bubble Rising in Microgravity Field

In this paper, bubble dynamics in a microgravity field is studied applying lattice Boltzmann method. The results are tested for simple bubble rising with grid resolution of three different grid sizes in two different times. Bubble deformation and its movement is compared with a simple bubble rising. Also, Effect of the frequency of microgravity field is studied on bubble dynamics and its deformation for two different values of frequency, f = 100 and f = 1000. Results demonstrated that frequency has a great effect on bubble movement, its deformation and the time of its vibration.
