Abstract

In this chapter we will use the acronym WFDR for water friction drag reduction to describe the general reduction of the frictional force of a hull wetted surface in water flow and air drag reduction (ADR) to describe achievement of reduction using air as a lubricant. If the local skin friction force on a surface in water flow is τw, then the local skin friction coefficient CF can be defined as:where ρ is the water density and U0 is the inflow velocity.
