An Analysis of Uniform Injection of a Drag-Reducing Fluid into a Turbulent Boundary Layertion into a turbulent boundary layer on a flat plate or slender body of revolution. This evaluation is necessary in order to determine the feasibility of using polymer solutions to reduce skin friction drag on marine vehicles. Uniform injection is chosen for analysis since it raises the additive con

Boundary-Layer Tripping with Emphasis on Hypersonic Flowsic speeds is small; however, certain shapes exhibit the advantageous characteristic of having drag coefficients which were relatively independent of roughness height over a restricted range of the variables tested.
