I am trying to simulate the movement of an air bubble submerged in liquid due to thermocapillary effect in microgravity condition. I am now considering moving mesh, laminar flow, heat transfer in fluids, non isothermal flow, marangoni effect. For the bubble movement into the liquid what physics I should use? I am now trying phase field method. If you have any other suggestions what physics and study or the similar simulation file, I should use, that will be very helpful. Thanks in advance.
