Abstract: Based on the theories of wall turbulent boundary layer and turbulent bursting process, typical underwater turbulence drag reduction technologies at present were analyzed and summarized in general. Firstly the drag reduction technologies were classed by the basic characteristics of wall turbulent boundary layer affected by every drag reduction technology. Then five kinds of feasible underwater turbulent drag reduction ways were gain, which were: (1) retaining or extending laminar flow region, (2) disturbing burst; (3) insulating surface from water, (4) augmenting turbulent damp, (5) changing surface attributes. The conclusions summarized in the paper could be used for the further research of turbulent drag reduction.
