| Abstract: | Liquid metal is an important energy transport carrier in nuclear fusion reactor, accelerator-driven sub critical system, spallation neutron source device, etc. The liquid metal flow velocity measurement is very important for the safe operation of these devices. Through experiments and numerical simulation, we study the gas bubble ascending motion in the static non-transparent liquid metal GaInSn. Numerical simulation method uses the turbulent two-equation model and VOF method for interface capturing. The experimental results are in good agreement with numerical simulation results. The large bubble oscillates in liquid metal with small amplitude in horizontal direction. |
