Based on N-S equation and two-phase model, the wake of a two-propeller ship is simulated. The bubble's birth, growth, break up and death can be analized though the volume fraction of the vapor in the sea water. The time and space charactes of the near field and far field are obtained. The results show that in the near field of the wake, the volume fraction of the vapor attenuates as the power law, and in the far field of the wake, the volume fraction of the vapor attenuates as the exponent law. The optics experiment is carried out and the results are consistent with the simulation results.
