초록

A process for reducing skin friction and inhibiting the effects of liquid turbulence in a system involving the flow of a liquid along the surface of a body, e.g. a marine vehicle, includes injecting a drag reducing polymer into the valleys of adjacent, evenly spaced, longitudinal grooves extending along the length of the surface of the body, so that the rate of diffusion of the polymer from individual grooves into the liquid flow is predictably controlled by the groove dimensions. When the polymer has diffused over the tips of the grooves into the near w...

A process for reducing skin friction and inhibiting effects of liquid turbulence, comprising providing a body having an exterior surface over which a fluid flows, forming a multiplicity of adjacent, evenly spaced, longitudinal grooves extending along an entire length of the surface, such that the grooves are parallel to the flow over the surface, providing each of the multiplicity of grooves with small surface projections such that each groove has increased frictional holding power, injecting a drag reducing polymer into each individual groove valley at ...
