Drag Reduction and Adaptive Boundary Conditions

Abstract

This report considers the problem of increasing the maximum speed at which the boundary layer of a body in water can remain in laminar flow. It is shown that substantial improvement can be made by modifying the boundary conditions of the linear stability problem. The concern of affecting the turbulence itself to reduce drag is not addressed.
