An improved meshless numerical method (MPS-MAFL) is utilized to simulate single Taylor bubble rising in liquid LBE to study its hydrodynamic characteristics. The computational region is a circular tube in which the liquid is described using discretized particles by non-uniform grid scheme. The gas-liquid interface was approximately treated as a free surface boundary and nonslip conditions are applied to the tube wall. Several simulation results and corresponding analysis including Taylor bubble propagation procedure, velocity profile around bubble nose and in the wake region as well as in the falling film are presented. Some experimental results and CFD numerical simulations from other researchers are compared with the present study as validation. The simulation results agree well with both theoretical analysis and experimental results, which demonstrate the reasonable selection of model as well as the accuracy and reliability of moving particle method (MPS-MAFL).
