      In this paper,the rising process of a single bubble in a complex channel consisting three half-circle throats was investigated by the lattice Boltzmann method.To analyze the influence of the complex channel on the motion characteristics of the bubble,the bubble shape,moving trajectory and bubble velocity during the rising process were studied,respectively.The result indicates that during the rising process,due to the influence of the surface,the bubble shape is deformed seriously,and the moving trajectory is deflected.By comparing with the experimental data,the simulations were validated.The results show that the lattice Boltzmann method is suitable for simulating the two-phase flows in the complex channel.
