Fluid resistance reducing method and resistance reducing propulsion device

摘要

A fluid resistance reducing method and a resistance reducing propulsion device are disclosed, wherein vane-shaped devices are inserted in the fluid at a certain interval along a vertical direction to a moving velocity direction of the fluid, and thus the fluid is divided into several limited zones to limit the fluid and solidify moving state; resultantly the fluid is prevented from directly crashing with fixed wall of a surface of an object to be resistance-reduced and thus a moving velocity direction of the vane-shaped device accords with a predetermined direction of a tangent line of the fixed wall and reaction force on the fluid provides a centripetal force for the fluid to turn, so as to force the fluid to gradually change the velocity direction along the fixed wall and manually intervene with parts of the object to force the fluid near a boundary face to moves stratifiedly and orderly.
