2D Rising Bubble Heat Transfer
2D simulation of a rising bubble with heat transfer. The bubble, lighter then the surrounding fluid, rises and moves towards the heat interface (green color) . The non-dimensional numbers used in this simulations were Re = 200, Sc = 1000, We = 10, mu_in = 0.5, mu_out = 1.0, rho_out = 1.0, rho_in = 0.01. On the right ha nd side, the inner and interface meshes are shown. It can be seen that after a certain period of time the bubble does not rise straight, instead the bubble oscillates from one side to another and changes its shape.
