The influence of the external flow on the liquid-vapor phase transition is numerically studied in this work. The bubble growth and departure from a heated surface in a shear flow is realized through a pseudo-potential based lattice Boltzmann method. The benchmark test of the pool boiling induced by a single heated plate is adopted to validate the present method. The averaged heat flux, the bubble releasing frequency and flow features are presented, along with the effects of the flow intensity on them. It is shown that the external flow significantly enhances the heat transfer of the system in two respects: increasing the averaged heat flux and the bubble releasing frequency.
