In order to study the influence of Reynolds Number and micro-bubbles volume fraction on reducing ship friction, the numerical stimulation of friction reduction by micro-bubbles is made on the two-dimension vessel by injecting bubbles from perforated plates fixed at the bow of vessel’s bilge.

Microbubble drag reduction technology is developed in recent three decades, many scholars at home and abroad have done a large number of experimental and theoretical researches on the micr-bubble drag reduction , and the good drag reduction effect has been tested for the trial.

And then the research actualities of riblet surface drag reduction technology,microbubble drag reduction technology and hydrophobic/superhydrophobic surface drag reduction technology are expounded through experimental and theoretical researches with drag reduction mechanisms purposively emphasized.
